737eb76789 Use file_location for md_reader's ptr_loc
Also make it public, so that clients can use the location for error
reporting.

	* read-md.h (md_reader::ptr_loc): Moved from read-md.c.
	Use file_location instead of separate fields.
	(md_reader::set_md_ptr_loc): Take a file_location instead of a
	separate filename and line number.

f6e5e4b83b [rs6000] Fix ambiguous .md attribute uses
This patch is part of a series that fixes ambiguous attribute
uses in .md files, i.e. cases in which attributes didn't use
<ITER:ATTR> to specify an iterator, and in which <ATTR> could
have different values depending on the iterator chosen.

No behavioural change -- produces the same code as before except
for formatting and line numbers.

4e62f891cd runtime: expose the g variable
Currently, getg is implemented in C, which loads the thread-local
    g variable. The g variable is declared static in C.
    
    This CL exposes the g variable, so it can be accessed from the Go
    side. This allows the Go compiler to inline getg calls to direct
    access of g.
    
    Currently, the actual inlining is only implemented in the gollvm
    compiler. The g variable is thread-local and the compiler backend
    may choose to cache the TLS address in a register or on stack. If
    a thread switch happens the cache may become invalid. I don't
    know how to disable the TLS address cache in gccgo, therefore
    the inlining of getg is not implemented. In the future gccgo may
    gain this if we know how to do it safely.

61fba2674f [Darwin, testsuite] Remove unused test.
During GCC-9, the codegen for unreachable switch case statements changed
such that the (undefined) behaviour of reaching such statements is directed
to one of the existing switch cases.  This means that the testcase which
deals with the old behaviour can no longer work (and there is nothing to test
with it).  The [Darwin-specific] test is now redundant and can be removed.

b847405ade allow EH to escape from GIMPLE_EH_ELSE ELSE block
The only preexisting use of GIMPLE_EH_ELSE, for transactional memory
commits, did not allow exceptions to escape from the ELSE path.  The
trick it uses to allow the ELSE path to see the propagating exception
does not work very well if the exception cleanup raises further
exceptions: the ELSE block is configured to handle exceptions in
itself.  This confuses the heck out of CFG and EH cleanups.

Basing the lowering context for the ELSE block on outer_state, rather
than this_state, gets us the expected enclosing handler.

0d67cd380d Define __type_identity_t alias and use for string_view
This defines the equivalent of C++2a's std::type_identity_t alias but
for use in C++11 and later. This can be used to replace __detail::__idt
in the string_view headers, which previously used common_type_t because
the one argument specialization of common_type_t was simply the identity
transform (which is no longer true).

72ab1c51b6 Relax vector_builder::elt sanity check
I'd made it a precondition of vector_builder::elt that the encoding
must have been fully populated and that all implicit elements are
therefore defined.  But for one of the AArch64 patches I'm working on,
it'd be convenient to be able to look back at previous elements while
building up the encoding.  This patch therefore makes the assert
specific to implicit elements only.

This patch is part of a series that fixes ambiguous attribute

have different values depending on the iterator chosen.

divide permutations.

d281492de8 Support multiple operand counts for .md @ patterns
This patch extends the support for "@..." pattern names so that
the patterns can have different numbers of operands.  This allows
things like binary and ternary operations to be handled in a
consistent way, a bit like optabs.  The generators assert that
the number of operands passed is correct for the underlying
instruction.

Also, replace_operands_with_dups iterated over the old rtx format
even after having decided to do a replacement, which broke with
match_operator.
