MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
Make the n64 ABI the default for 64-bit Linux targets specified with
`-gnuabi64' suffix included in the target triplet, for configurations
such as the Debian mips64el and mips64r6el ports. Adjust testsuite
configuration accordingly.
There are the following regressions with the new target triplet:
mips64-linux-gnuabi64 +FAIL: readelf -S bintest
mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
mips64el-linux-gnuabi64 +FAIL: readelf -S bintest
mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
The `readelf' issue comes from a difference in section headers produced
that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template
does not match. While there has been a precedent it does not appear to
me that there is a clear advantage from adding more and more variations
to the template rather than forking the existing template into multiple
ones for a more exact match. So this is best deferred to a separate
discussion.
The MIPS reloc estimation issue is an actual bug in `objdump', which
discards a number of trailing entries from output here for n64 composed
relocations:
DYNAMIC RELOCATION RECORDS
OFFSET TYPE VALUE
0000000000000000 R_MIPS_NONE *ABS*
0000000000000000 R_MIPS_NONE *ABS*
and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not
match even though ELF output produced is correct according to `readelf':
Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries:
Offset Info Type Sym. Value Sym. Name
000000000000 000000000000 R_MIPS_NONE
Type2: R_MIPS_NONE
Type3: R_MIPS_NONE
000000010000 000300001203 R_MIPS_REL32 0000000000010010 foo@@V2
Type2: R_MIPS_64
Type3: R_MIPS_NONE
As a genuine bug this has to be handled separately.
