In optimized builds, visit(ir_expression *) experiences inlining with gcc that leads the function to have a roughly 32KB stack frame. This is a problem given that the function is called recursively. In non-optimized builds, the stack frame is much smaller, hence one gets crashes that happen only in optimized builds. Arguably there is a compiler bug or at least severe misfeature here. In any case, the easy thing to do for now seems to be moving the bulk of the non-recursive code into a separate function. This is sufficient to convince my version of gcc not to blow up the stack frame of the recursive part. Just to be sure, add the gcc-specific noinline attribute to prevent this bug from reoccuring if inliner heuristics change. v2: put ATTRIBUTE_NOINLINE into macros.h Cc: "11.1 11.2" <mesa-stable@lists.freedesktop.org> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95133 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95026 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92850 Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu> Reviewed-by: Rob Clark <robdclark@gmail.com> |
