build log

Hi,

On x32 system, the dev-libs/blake3 build includes apparently dysfunctional
amd64 assembly code.  This leads to segmentation faults in ccache and in the
blake3 test suite (src_test only does anything in 1.5.3 package, but the
problem exists in prior versions too).

Configuring with -DBLAKE3_SIMD_TYPE=x86-intrinsics avoids the hand-written
assembly code and is sufficient to produce a working library which passes
tests.

I suggest the ebuild should set this configuration on x32 ABI.

assembly code fix

Another option is to fix assembly code. This patch fixes issue for me, but could you please test, so I will be able to send it upstream?

Nick, could you give it a go?

Altered asm patch

I had to adjust the filenames to get it to be applied by the ebuild, and fix up what looks to be a small typo (change qword to dword in one of the #else blocks).

But with this one in /etc/portage/patches the package installs and passes tests at least.
