https://bugs.freedesktop.org/show_bug.cgi?id=107369 --- Comment #16 from Stuart Young --- There's a fix for this in the Debian experimental package for libclc. If you haven't already done so and this bug affects you, please test and give feedback on the Debian bug.

Hi, sorry for the late reply. given the already strained time/resources, this is not a priority. The fix to this bug is for Debian to stop modifying libclc cflags. -- You are receiving this mail because: You are the QA Contact for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=107369 --- Comment #12 from Gian-Carlo Pascutto --- So the bugs are: 1) Debian adding flags even if they don't make sense (i.e. stack protection on GPU code). Should be filed in Debian against libclc. 2) LLVM respecting that flag even if it shouldn't. Should be checked if it still happens with LLVM 7 and filed against LLVM if so. -- You are receiving this mail because: You are the assignee for the bug.

[Mesa-dev] [Bug 107369] "volatile" in OpenCL code not recognized when compiling with -fstack-protector
https://bugs.freedesktop.org/show_bug.cgi?id=107369 --- Comment #11 from Jan Vesely --- GPUs don't really have a stack (not for data anyway) and AMDGCN backend currently inlines all function calls anyway. I'm not sure what kind of checks the flag adds. If anyone can upload the different libclc bitcode it should be easy to spot. My guess would be that it adds some initialized global variables used in internal checks. This is illegal in CLC. only variables in constant address space can have initializers. IMO Debian should not be arbitrarily adding compilation flags unless they know what they're doing and they have tested the resulting package. local variables are stored in private address space which is backed either by register file, or private buffers. using volatile, to control where it is located, is a rather hacky workaround of suboptimal register allocation/instruction scheduling. Reporting a llvm bug with a reproducer can help. it'd need to be reproducible using llvm-7, there are no further releases of llvm-5 or 6 planned. -- You are receiving this mail because: You are the assignee for the bug.
