Big merge of changes to gofrontend repo that were postponed due to the GCC release freeze. * go-backend.c: Include "go-c.h". * go-gcc.cc (Gcc_backend::write_export_data): New method. * go-gcc.cc (Gcc_backend::Gcc_backend): Declare __builtin_prefetch. * Make-lang.in (GO_OBJS): Add go/wb.o. commit 884c9f2cafb3fc1decaca70f1817ae269e4c6889 Author: Than McIntosh <thanm@google.com> Date: Mon Jan 23 15:07:07 2017 -0500 compiler: insert additional conversion for type desc ptr expr Change the method Type::type_descriptor_pointer to apply an additional type conversion to its result Bexpression, to avoid type clashes in the back end. The backend expression for a given type descriptor var is given a type of "_type", however the virtual calls that create the variable use types derived from _type, hence the need to force a conversion. Reviewed-on: https://go-review.googlesource.com/35506 commit 5f0647c71e3b29eddcd0eecc44e7ba44ae7fc8dd Author: Than McIntosh <thanm@google.com> Date: Mon Jan 23 15:22:26 2017 -0500 compiler: insure tree integrity in Call_expression::set_result Depending on the back end, it can be problematic to reuse Bexpressions (passing the same Bexpression to more than one Backend call to create additional Bexpressions or Bstatements). The Call_expression::set_result method was reusing its Bexpression input in more than one tree context; the fix is to pass in an Expression instead and generate multiple Bexpression references to it within the method.

The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

Reviewed-on: https://go-review.googlesource.com/39923 commit 8b01ef1e9176d20f4c9e667972fe031069a4d057 Author: Ian Lance Taylor <iant@golang.org> Date: Thu Apr 13 07:00:35 2017 -0700 compiler: add ptrdata computations and expressions For the upcoming Go 1.8 GC we need to compute the "ptrdata" of a type: the number of bytes in the type that can contain pointers. For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

Since we don't need to know that struct in C, rather than fix the general case, just punt if the struct has multiple sink fields. After the conversion to the Go 1.8 GC, we may be able to get rid of the C header file anyhow. I'm not sure yet.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

\`configure' configures package-unused version-unused to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]

--enable-version-specific-runtime-libs
Specify that runtime libraries should be installed
in a compiler-specific directory
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--without-libffi don't use libffi
--without-libatomic don't use libatomic
--with-system-libunwind use installed libunwind
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
GOC Go compiler command
GOCFLAGS Go compiler flags
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.

The backend expression for a given type descriptor var is given a type of "_type", however the virtual calls that create the variable use types derived from _type, hence the need to force a conversion.

The Call_expression::set_result method was reusing its Bexpression input in more than one tree context; the fix is to pass in an Expression instead and generate multiple Bexpression references to it within the method.

If the next memory block is not live, we now have a live pointer to a dead block, which will unnecessarily keep the block alive. That wastes space, and with the new Go 1.8 GC (not yet committed) will trigger an error when using GODEBUG=gccheckmark=1. This changes the implementation of slice expressions to not move the pointer if the resulting string length or slice capacity is 0. When the length/capacity is zero, the pointer is never used anyhow.

For details see https://blog.golang.org/go15gc. This changes the gofrontend code to emit write barriers as needed. This is in preparation for future changes. At the moment the write barriers will do nothing. They test runtime.writeBarrier.enabled, which will never be non-zero. They call simple functions which just do a move without doing any of the other operations required by the write barrier.

A gcprog describes where the pointers are in the type, using a simple bytecode machine that supports repeating bits. The effect is to permit using much less space to describe arrays. The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources. This change adds code to the compiler to generate a gcprog. The code is not used by anything yet, it is just compiled. It will be used when we switch over to the Go 1.8 garbage collector.

For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

There are structs with single sink fields that we want to write out, such as finblock. As it happens, though, the Go 1.8 runtime has a struct with two sink fields, gcControllerState, which will produce a C definition with two fields named "_", which will fail. Since we don't need to know that struct in C, rather than fix the general case, just punt if the struct has multiple sink fields. After the conversion to the Go 1.8 GC, we may be able to get rid of the C header file anyhow. I'm not sure yet.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

Issue golang/go#19200 Reviewed-on: https://go-review.googlesource.com/42051 commit 0fb550083ae474fb964435927b899ec8e4b62771 Author: Ian Lance Taylor <iant@golang.org> Date: Wed Nov 16 21:12:53 2016 -0800 runtime: copy garbage collector from Go 1.8 runtime This giant patch replaces the old Go 1.4 memory allocator and garbage collector with the new Go 1.8 code. The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

The goc2c program was my first contribution to the gc repository that was more than 100 lines: https://github.com/golang/go/commit/2b57a1124e87b0dc8bc1ff6899297b4d7d6e74f2 The program was used in gc for a few years under various guises but was finally removed in https://golang.org/cl/132680043. Now we can remove it from gofrontend as well.

The code that was doing this addition did not update the flag that tracks whether the package being compiled needs an initializer function, which resulted in the call in question being left out of the final generated code in certain cases. Fix is to change Gogo::add_gc_root() to update the "needs init" flag.

The backend expression for a given type descriptor var is given a type of "_type", however the virtual calls that create the variable use types derived from _type, hence the need to force a conversion.

The Call_expression::set_result method was reusing its Bexpression input in more than one tree context; the fix is to pass in an Expression instead and generate multiple Bexpression references to it within the method.

That wastes space, and with the new Go 1.8 GC (not yet committed) will trigger an error when using GODEBUG=gccheckmark=1.

A gcprog describes where the pointers are in the type, using a simple bytecode machine that supports repeating bits. The effect is to permit using much less space to describe arrays. The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

There are structs with single sink fields that we want to write out, such as finblock. As it happens, though, the Go 1.8 runtime has a struct with two sink fields, gcControllerState, which will produce a C definition with two fields named "_", which will fail.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

We have to scan it for pointers, but since registers don't necessarily hold pointers we have to scan it conservatively. That means that it should not have a pointer type, since the GC will always scan pointers. Instead it needs special treatment to be scanned conservatively. The current GC doesn't care when a pointer type holds a non-pointer, but the Go 1.8 GC does. For the current GC this means we have to explicitly scan the g_ucontext_t values in a G.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

That wastes space, and with the new Go 1.8 GC (not yet committed) will trigger an error when using GODEBUG=gccheckmark=1.

A gcprog describes where the pointers are in the type, using a simple bytecode machine that supports repeating bits. The effect is to permit using much less space to describe arrays. The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

Reviewed-on: https://go-review.googlesource.com/39923 commit 8b01ef1e9176d20f4c9e667972fe031069a4d057 Author: Ian Lance Taylor <iant@golang.org> Date: Thu Apr 13 07:00:35 2017 -0700 compiler: add ptrdata computations and expressions For the upcoming Go 1.8 GC we need to compute the "ptrdata" of a type: the number of bytes in the type that can contain pointers. For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

Reviewed-on: https://go-review.googlesource.com/39923 commit 8b01ef1e9176d20f4c9e667972fe031069a4d057 Author: Ian Lance Taylor <iant@golang.org> Date: Thu Apr 13 07:00:35 2017 -0700 compiler: add ptrdata computations and expressions For the upcoming Go 1.8 GC we need to compute the "ptrdata" of a type: the number of bytes in the type that can contain pointers. For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

Big merge of changes to gofrontend repo that were postponed due to the GCC release freeze. * go-backend.c: Include "go-c.h". * go-gcc.cc (Gcc_backend::write_export_data): New method. * go-gcc.cc (Gcc_backend::Gcc_backend): Declare __builtin_prefetch. * Make-lang.in (GO_OBJS): Add go/wb.o. commit 884c9f2cafb3fc1decaca70f1817ae269e4c6889 Author: Than McIntosh <thanm@google.com> Date: Mon Jan 23 15:07:07 2017 -0500 compiler: insert additional conversion for type desc ptr expr Change the method Type::type_descriptor_pointer to apply an additional type conversion to its result Bexpression, to avoid type clashes in the back end. The backend expression for a given type descriptor var is given a type of "_type", however the virtual calls that create the variable use types derived from _type, hence the need to force a conversion. Reviewed-on: https://go-review.googlesource.com/35506 commit 5f0647c71e3b29eddcd0eecc44e7ba44ae7fc8dd Author: Than McIntosh <thanm@google.com> Date: Mon Jan 23 15:22:26 2017 -0500 compiler: insure tree integrity in Call_expression::set_result Depending on the back end, it can be problematic to reuse Bexpressions (passing the same Bexpression to more than one Backend call to create additional Bexpressions or Bstatements). The Call_expression::set_result method was reusing its Bexpression input in more than one tree context; the fix is to pass in an Expression instead and generate multiple Bexpression references to it within the method.

The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

Reviewed-on: https://go-review.googlesource.com/39923 commit 8b01ef1e9176d20f4c9e667972fe031069a4d057 Author: Ian Lance Taylor <iant@golang.org> Date: Thu Apr 13 07:00:35 2017 -0700 compiler: add ptrdata computations and expressions For the upcoming Go 1.8 GC we need to compute the "ptrdata" of a type: the number of bytes in the type that can contain pointers. For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

The backend expression for a given type descriptor var is given a type of "_type", however the virtual calls that create the variable use types derived from _type, hence the need to force a conversion.

The Call_expression::set_result method was reusing its Bexpression input in more than one tree context; the fix is to pass in an Expression instead and generate multiple Bexpression references to it within the method.

If the next memory block is not live, we now have a live pointer to a dead block, which will unnecessarily keep the block alive. That wastes space, and with the new Go 1.8 GC (not yet committed) will trigger an error when using GODEBUG=gccheckmark=1.

A gcprog describes where the pointers are in the type, using a simple bytecode machine that supports repeating bits. The effect is to permit using much less space to describe arrays. The format is described in runtime/mbitmap.go in the docs for runGCProg. This is not yet added to the gofrontend, but can be seen in the gc sources.

For types that do not contain pointers this number is zero. For many types it is a number larger than zero but smaller than the total size of the type. The Go 1.8 GC uses this number to make loops looking for pointers run faster by not scanning the suffix of a value that can not contain a pointer. Unfortunately there are two subtly different definitions of ptrdata, and we need both. The first is the simple one: the prefix that can contain pointers. The second is the number of bytes described by the gcprog for the type. Recall that we describe the exact position of pointers in a type using either a ptrmask or a gcprog. The ptrmask is simpler, the gcprog uses less space. We use the gcprog for large types, currently defined as types that are more than 2048 bytes. When the Go 1.8 runtime expands a gcprog, it verifies that the gcprog describes exactly the same number of bytes as the ptrdata field in the type descriptor. If the last pointer-containing portion of a type is an array, and if the elements of the array have a ptrdata that is less than the size of the element type, then the simple definition of the ptrdata will not include the final non-pointer-containing bytes of the last element of the array. However, the gcprog will define the array using a repeat count, and will therefore include the full size of the last element of the array. So for a type that needs a gcprog, the ptrdata field in the type descriptor must be the size of the data described by the gcprog, and that is not necessarily the same as the simple ptrdata. It might seem that we can always use the gcprog version of the ptrdata calculation, since that is what will appear in a type descriptor, but it turns out that for global variables we always use a ptrmask, not a gcprog, even if the global variable is large. This is because gcprogs are handled by expanding them into a ptrmask at runtime, and for a global variable there is no natural place to put the ptrmask. Simpler to always use the ptrmask. That means that we need to describe the size of the ptrmask, and that means that we need an expression for the simple form of the ptrdata. This CL implements the ptrdata calculation. This code is not actually used yet. It will be used later when the Go 1.8 GC is committed.

This is often used to get more stack space; the gofrontend uses a different stack growth mechanism that does not require changing g's, so we've been running with a version of systemstack that keeps the same g. However, the garbage collector has various tests to verify that it is running on g0 rather than on a normal g. For simplicity, change the gofrontend version of systemstack to change to a different g just as the gc toolchain does. This permits us to uncomment some sanity checks in notetsleep. Doing that requires us to fix up a couple of places where C code calls {start,stop}TheWorldWithSema while not on g0. Note that this does slow down some code in the runtime package unnecessarily. It may be useful to find some places where the runtime calls systemstack only to get more stack space and change it to use some other function. That other function would act like systemstack in the gc toolchain but simply call the argument in the gofrontend.

The memory allocator is fairly similar, though now written in Go rather than C. The garbage collector is completely different. It now uses ptrmask and gcprog information, which requires changes in the compiler and the reflect package as well as the runtime. And, of course, the garbage collector now runs concurrently with program execution. In the gc toolchain the garbage collector is strict and precise at all levels. In the gofrontend we do not have stack maps, so stacks, and register values, are collected conservatively. That means that an old, no longer used, pointer on a stack or in a register can cause a memory object to live longer than it should. That in turns means that we must disable some checks for invalid pointers in the garbage collection code. Not only can we get an invalid pointer on the stack; the concurrent nature of the collector means that we can in effect resurrect a block that was already unmarked but that the collector had not yet gotten around to freeing, and that block can in turn point to other blocks that the collector had managed to already free. So we must disable pointer checks in general. In effect we are relying on the fact that the strict pointer checks in the gc toolchain ensure that the garbage collector is correct, and we just assume that it is correct for the gofrontend since we are using the same code.

The code that was doing this addition did not update the flag that tracks whether the package being compiled needs an initializer function, which resulted in the call in question being left out of the final generated code in certain cases.
