/* Here is a brief description of the MIPS ECOFF symbol table, by
|
|
|
|
|
Michael Meissner. The MIPS symbol table has the following pieces:
|
|
|
|
|
|
|
|
|
|
Symbolic Header
|
|
|
|
|
|
|
|
|
|
|
+-- Auxiliary Symbols
|
|
|
|
|
|
|
|
|
|
|
+-- Dense number table
|
|
|
|
|
|
|
|
|
|
|
+-- Optimizer Symbols
|
|
|
|
|
|
|
|
|
|
|
+-- External Strings
|
|
|
|
|
|
|
|
|
|
|
+-- External Symbols
|
|
|
|
|
|
|
|
|
|
|
+-- Relative file descriptors
|
|
|
|
|
|
|
|
|
|
|
+-- File table
|
|
|
|
|
|
|
|
|
|
|
+-- Procedure table
|
|
|
|
|
|
|
|
|
|
|
+-- Line number table
|
|
|
|
|
|
|
|
|
|
|
+-- Local Strings
|
|
|
|
|
|
|
|
|
|
|
+-- Local Symbols
|
|
|
|
|
|
|
|
|
|
The symbolic header points to each of the other tables, and also
|
|
|
|
|
contains the number of entries. It also contains a magic number
|
|
|
|
|
and MIPS compiler version number, such as 2.0.
|
|
|
|
|
|
|
|
|
|
The auxiliary table is a series of 32 bit integers, that are
|
|
|
|
|
referenced as needed from the local symbol table. Unlike standard
|
|
|
|
|
COFF, the aux. information does not follow the symbol that uses
|
|
|
|
|
it, but rather is a separate table. In theory, this would allow
|
|
|
|
|
the MIPS compilers to collapse duplicate aux. entries, but I've not
|
|
|
|
|
noticed this happening with the 1.31 compiler suite. The different
|
|
|
|
|
types of aux. entries are:
|
|
|
|
|
|
|
|
|
|
1) dnLow: Low bound on array dimension.
|
|
|
|
|
|
|
|
|
|
2) dnHigh: High bound on array dimension.
|
|
|
|
|
|
|
|
|
|
3) isym: Index to the local symbol which is the start of the
|
|
|
|
|
function for the end of function first aux. entry.
|
|
|
|
|
|
|
|
|
|
4) width: Width of structures and bitfields.
|
|
|
|
|
|
|
|
|
|
5) count: Count of ranges for variant part.
|
|
|
|
|
|
|
|
|
|
6) rndx: A relative index into the symbol table. The relative
|
|
|
|
|
index field has two parts: rfd which is a pointer into the
|
|
|
|
|
relative file index table or ST_RFDESCAPE which says the next
|
|
|
|
|
aux. entry is the file number, and index: which is the pointer
|
|
|
|
|
into the local symbol within a given file table. This is for
|
|
|
|
|
things like references to types defined in another file.
|
|
|
|
|
|
|
|
|
|
7) Type information: This is like the COFF type bits, except it
|
|
|
|
|
is 32 bits instead of 16; they still have room to add new
|
|
|
|
|
basic types; and they can handle more than 6 levels of array,
|
|
|
|
|
pointer, function, etc. Each type information field contains
|
|
|
|
|
the following structure members:
|
|
|
|
|
|
|
|
|
|
a) fBitfield: a bit that says this is a bitfield, and the
|
|
|
|
|
size in bits follows as the next aux. entry.
|
|
|
|
|
|
|
|
|
|
b) continued: a bit that says the next aux. entry is a
|
|
|
|
|
continuation of the current type information (in case
|
|
|
|
|
there are more than 6 levels of array/ptr/function).
|
|
|
|
|
|
|
|
|
|
c) bt: an integer containing the base type before adding
|
|
|
|
|
array, pointer, function, etc. qualifiers. The
|
|
|
|
|
current base types that I have documentation for are:
|
|
|
|
|
|
|
|
|
|
btNil -- undefined
|
|
|
|
|
btAdr -- address - integer same size as ptr
|
|
|
|
|
btChar -- character
|
|
|
|
|
btUChar -- unsigned character
|
|
|
|
|
btShort -- short
|
|
|
|
|
btUShort -- unsigned short
|
|
|
|
|
btInt -- int
|
|
|
|

|
|
|
|
|
btLong -- long
|
|
|
|
|
btULong -- unsigned long
|
|
|
|
|
btFloat -- float (real)
|
|
|
|
|
btDouble -- Double (real)
|
|
|
|
|
btStruct -- Structure (Record)
|
|
|
|
|
btUnion -- Union (variant)
|
|
|
|
|
btEnum -- Enumerated
|
|
|
|
|
btTypedef -- defined via a typedef isymRef
|
|
|
|
|
btRange -- subrange of int
|
|
|
|
|
btSet -- pascal sets
|
|
|
|
|
btComplex -- fortran complex
|
|
|
|
|
btDComplex -- fortran double complex
|
|
|
|
|
btIndirect -- forward or unnamed typedef
|
|
|
|
|
btFixedDec -- Fixed Decimal
|
|
|
|
|
btFloatDec -- Float Decimal
|
|
|
|
|
btString -- Varying Length Character String
|
|
|
|
|
btBit -- Aligned Bit String
|
|
|
|
|
btPicture -- Picture
|
|
|
|
|
btVoid -- Void (MIPS cc revision >= 2.00)
|
|
|
|
|
|
|
|
|
|
d) tq0 - tq5: type qualifier fields as needed. The
|
|
|
|
|
current type qualifier fields I have documentation for
|
|
|
|
|
are:
|
|
|
|
|
|
|
|
|
|
tqNil -- no more qualifiers
|
|
|
|
|
tqPtr -- pointer
|
|
|
|
|
tqProc -- procedure
|
|
|
|
|
tqArray -- array
|
|
|
|
|
tqFar -- 8086 far pointers
|
|
|
|
|
tqVol -- volatile
|
|
|
|
|
|
|
|
|
|
The dense number table is used in the front ends, and disappears by
|
|
|
|
|
the time the .o is created.
|
|
|
|
|
|
|
|
|
|
With the 1.31 compiler suite, the optimization symbols don't seem
|
|
|
|
|
to be used as far as I can tell.
|
|
|
|
|
|
|
|
|
|
The linker is the first entity that creates the relative file
|
|
|
|
|
descriptor table, and I believe it is used so that the individual
|
|
|
|
|
file table pointers don't have to be rewritten when the objects are
|
|
|
|
|
merged together into the program file.
|
|
|
|
|
|
|
|
|
|
Unlike COFF, the basic symbol & string tables are split into
|
|
|
|
|
external and local symbols/strings. The relocation information
|
|
|
|
|
only goes off of the external symbol table, and the debug
|
|
|
|
|
information only goes off of the internal symbol table. The
|
|
|
|
|
external symbols can have links to an appropriate file index and
|
|
|
|
|
symbol within the file to give it the appropriate type information.
|
|
|
|
|
Because of this, the external symbols are actually larger than the
|
|
|
|
|
internal symbols (to contain the link information), and contain the
|
|
|
|
|
local symbol structure as a member, though this member is not the
|
|
|
|
|
first member of the external symbol structure (!). I suspect this
|
|
|
|
|
split is to make strip easier to deal with.
|
|
|
|
|
|
|
|
|
|
Each file table has offsets for where the line numbers, local
|
|
|
|
|
strings, local symbols, and procedure table starts from within the
|
2017-01-23 16:23:07 +01:00
|
|
|
|
global tables, and the indices are reset to 0 for each of those
|
1999-05-03 09:29:11 +02:00
|
|
|
|
tables for the file.
|
|
|
|
|
|
|
|
|
|
The procedure table contains the binary equivalents of the .ent
|
|
|
|
|
(start of the function address), .frame (what register is the
|
|
|
|
|
virtual frame pointer, constant offset from the register to obtain
|
|
|
|
|
the VFP, and what register holds the return address), .mask/.fmask
|
|
|
|
|
(bitmask of saved registers, and where the first register is stored
|
|
|
|
|
relative to the VFP) assembler directives. It also contains the
|
|
|
|
|
low and high bounds of the line numbers if debugging is turned on.
|
|
|
|
|
|
|
|
|
|
The line number table is a compressed form of the normal COFF line
|
|
|
|
|
table. Each line number entry is either 1 or 3 bytes long, and
|
|
|
|
|
contains a signed delta from the previous line, and an unsigned
|
|
|
|
|
count of the number of instructions this statement takes.
|
|
|
|
|
|
|
|
|
|
The local symbol table contains the following fields:
|
|
|
|
|
|
|
|
|
|
1) iss: index to the local string table giving the name of the
|
|
|
|

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense
number in a .T file (symbol table).)"
Copy the approach from `s_mips_ent' then and add `.aent' support to the
`.ent' pseudo-op handler shared between the ELF and ECOFF object file
format backends, by setting BSF_FUNCTION for the symbol requested.

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense

GAS: Consistently fix labels at the `.end' pseudo-op
Fix a functional regression with the `.end' pseudo-op, introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, and commit
dcd410fe1544 ("GNU as 2.14 on IRIX 6: crashes with shared libs"),
<https://sourceware.org/ml/binutils/2003-07/msg00415.html>, which caused
symbol values for labels placed between the end of a function's contents
and its terminating `.end' followed by one of the alignment pseudo-ops
to be different depending on whether either `-mdebug', or `-mno-pdr', or
neither of the command-line options is in effect, be it implied or
specified.
Given debug-label-end.s as follows and the `mips-linux' target we have:
$ cat debug-label-end.s
.text
.globl foo
.globl bar
.align 4, 0
.ent foo
foo:
nop
.aent bar
bar:
.insn
.end foo
.align 4, 0
.space 16
.globl baz
.ent baz
baz:
nop
.end baz
.align 4, 0
.space 16
$ as -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000004 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mdebug -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mno-pdr -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
8: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$
The reason is the call to `md_flush_pending_output', which in the case
of `mips*-*-*' targets expands to `mips_emit_delays', which in turn
calls `mips_no_prev_insn', which calls `mips_clear_insn_labels', which
clears the list of outstanding labels. That list is in turn consulted
in `mips_align', called in the interpretation of alignment directives,
and the labels adjusted to the current location.
A call to `md_flush_pending_output' is only made from `s_mips_end' and
then only if `-mpdr' is in effect, which is the default for `*-*-linux*'
and some other `mips*-*-*' targets. A call to `md_flush_pending_output'
is never made from `ecoff_directive_end', which is used in place of
`s_mips_end' when `-mdebug' is in effect. Consequently if `-mno-pdr' or
`-mdebug' is in effect the list of outstanding labels makes it through
to any alignment directive that follows and the labels are differently
interpreted depending on the command-lines options used. And we want
code produced to be always the same.
Call `md_flush_pending_output' unconditionally then in `s_mips_end' and
add such a call from `ecoff_directive_end' as well, as long as the macro
is defined. While `ecoff_directive_end' is shared among targets, the
only one other than `mips*-*-*' actually using it is `alpha*-*-*' and it
does not define `md_flush_pending_output'. So the semantics isn't going
to change for it and neither it has to have its `s_alpha_end' updated
or have code in `ecoff_directive_end' conditionalized.

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense
number in a .T file (symbol table).)"
Copy the approach from `s_mips_ent' then and add `.aent' support to the
`.ent' pseudo-op handler shared between the ELF and ECOFF object file
format backends, by setting BSF_FUNCTION for the symbol requested.
