[Mesa-dev] [Bug 109391] LTO Build fails
https://bugs.freedesktop.org/show_bug.cgi?id=109391 --- Comment #4 from Hi-Angel --- Please test the following patch, it should resolve the building problem. What it does is disables flto for specific files with assembly defined functions. It's okay since from a cursory look there's not much code except the assembly stuff. I should mention however, for some reason flto-optimized r600g works incorrectly for me. But this is irrelevant to the current problem, and in fact I've stopped using LTO build some months ago for that reason (yeah, LTO build with GCC worked for me too, I don't know why it broke recently). I wanted to bisect that back then, but screwed bisection up, and later I just didn't have motivation or time. -- You are receiving this mail because: You are the assignee for the bug.

[Mesa-dev] [Bug 109391] LTO Build fails
https://bugs.freedesktop.org/show_bug.cgi?id=109391 --- Comment #1 from Hi-Angel --- I just researched the problem, and it comes down to function declarations using assembly. Maybe there some __attribute__ needs to be added and what not, but I kind of stuck ATM, because the assembly code is in a generated header `build/src/glapi/gen/glapi_mapi_tmp.h`. I would appreciate if anybody acknowledged would tell what part of code is responsible for generating the header above. I hope to take a closer look on the weekend. -- You are receiving this mail because: You are the assignee for the bug.
