270 out of 284 tests get failed with SIGSEGV on ClearLinux because the ifunc
resolver resolve_half_to_float() tries to call unbound global function
igt_x86_features(). This patch fixes the issue by adding a F16C checking
local function.

**FAILURE**
Serious unknown changes coming with IGTPW_3510_full absolutely need to be
verified manually.
If you think the reported changes have nothing to do with the changes
introduced in IGTPW_3510_full, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.

* [igt-dev] [PATCH i-g-t] Fix global symbol loading failure in resolve function
@ 2019-09-30 9:30 brandon.hong

270 out of 284 tests get failed with SIGSEGV on ClearLinux because the ifunc
resolver resolve_half_to_float() tries to call unbound global function
igt_x86_features(). This patch fixes the issue by adding a F16C checking
local function.

The rules for this stuff seem to be poorly documented. But I did find
some docs that support this. So generally lgtm, just a few nitpicks
below...

igt_x86.c has HAVE_CPUID_H protection around this stuff.
I suppose we'd want the same here?

So, out of curiosity, why is the global function not bound?

Unfortunately, I do not have a clear answer why it's not bound.
I guess it's related to IFUNC lazy binding because I observed crash call stack related to glibc elf_machine_rela() and the crash didn’t happen when I call the same global function igt_x86_features() in rewritten generic FUNC igt_half_to_float() for testing.
