PowerPC __tls_get_addr arg parsing
The syntax we ended up with for -m32 -fPIC calls to __tls_get_addr is
rather weird.
bl __tls_get_addr+0x8000(gd0@tlsgd)@plt
This came about by accident, probably due to requiring the arg reloc
before the call reloc.
Of course the @plt really belongs with __tls_get_addr since it affects
the call rather than the call arg, and it isn't a great deal of
trouble to ensure the relocs are emitted in the correct order. This
patch supports a newer syntax, like so:
bl __tls_get_addr+0x8000@plt(gd0@tlsgd)
gas/
* config/tc-ppc.c (parse_tls_arg): New function, extracted..
(md_assembler): ..from here. Call it after parsing other
suffix modifiers too.
ld/
* testsuite/ld-powerpc/tls32.s: Test new @plt syntax.
