Bug ID: 28915
Summary: multiple piglit builtin-short* and builtin-ushort
tests fails
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Keywords: regression
Severity: normal
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: pavel.ondra...@email.cz
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Some failing tests:
builtin-char-upsample-1.0.generated
builtin-short-abs-1.0.generated
builtin-short-abs_diff-1.0.generated
builtin-short-add_sat-1.0.generated
builtin-short-clamp-1.1.generated
builtin-short-clz-1.0.generated
builtin-short-hadd-1.0.generated
builtin-ushort-abs-1.0.generated
and more
>From the tests its always just the 4, 8 and 16 subtests that fails, the 1 and 2
subtests pass.
The regression happened roughly between the beginning of May and end of July,
however since there was some long-time build breakage between llvm/clang and
libclc in the meantime I'm unable to bisect.
