Since one line touched has (DEFAULT_ABI == ABI_AIX || DEFAULT_ABI == ABI_ELFv2)
and powerpc64le-linux only adopts ABI_ELFv2, could you also test this
Hi All,
The following patch has been bootstrapped and regtested on powerpc64le-linux.
Normally, GPR2 is the TOC pointer and is defined as a fixed and non-volatile
register. However, it can be used as volatile for PCREL addressing. Therefore,
modified r2 to be non-fixed in FIXED_REGISTERS and
