Bug ID: 93089
Summary: mesa fails to check for gcc atomic primitives before
using them
Product: Mesa
Version: git
Hardware: Other
OS: OpenBSD
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev@lists.freedesktop.org
Reporter: j...@openbsd.org
QA Contact: mesa-dev@lists.freedesktop.org
The u_atomic.h macros assume the gcc atomic builtins are always available but
this is only the case on linux with the way the linux kernel fakes atomics when
the architecture does not provide them.
This concerns at least sparc < v9, hppa, sh, arm < v6, alpha and mips64.
mips64
undefined reference to `__sync_val_compare_and_swap_1'
alpha
undefined reference to `__sync_val_compare_and_swap_1'
i386 (should be avoidable with -march=i586 for cx8)
undefined symbol '__sync_val_compare_and_swap_8'
arm v4 abi
