--- Comment #4 from Arseny Solokha <asolokha at gmx dot com> --- (In reply to rguent...@suse.de from comment #3) > The > powerpc64[le]-linux crosses insist that -mcpu=860 requires a 64bit CPU... Which is strange, as 860 is a 32-bit CPU w/o FPU (perhaps a key here?) introduced in the 90s[1,2]. Other -mcpu values for reproduction of this ICE are all 4xx and 8xx (not including their corresponding fp variants) and e300c2 and ec603e, all of which also don't include a FPU. Additionally, the powerpcspe target doesn't need to specify -mcpu at all, as it implements floating-point and SIMD ISA with its specific non-standard SPE unit which reuses integer GPRs. % powerpc-e300c3-linux-gnu-gcc-9.0.0-alpha20181118 -v Using built-in specs.
