# We've had issues with gcc and 'asm goto' before, and we created a # 'asm_volatile_goto()' macro for that in the past: see commits # 3f0116c3238a ("compiler/gcc4: Add quirk for 'asm goto' miscompilation # bug") and a9f180345f53 ("compiler/gcc4: Make quirk for # asm_volatile_goto() unconditional"). # # Then, much later, we ended up removing the workaround in commit # 43c249ea0b1e ("compiler-gcc.h: remove ancient workaround for gcc PR # 58670") because we no longer supported building the kernel with the # affected gcc versions, but we left the macro uses around. # # Now, Sean Christopherson reports a new version of a very similar # problem, which is fixed by re-applying that ancient workaround. But the # problem in question is limited to only the 'asm goto with outputs' # cases, so instead of re-introducing the old workaround as-is, let's # rename and limit the workaround to just that much less common case. # # It looks like there are at least two separate issues that all hit in # this area: # # (a) some versions of gcc don't mark the asm goto as 'volatile' when it # has outputs: # # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619 # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420 # # which is easy to work around by just adding the 'volatile' by hand. # # (b) Internal compiler errors: # # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422 # # which are worked around by adding the extra empty 'asm' as a # barrier, as in the original workaround. # # but the problem Sean sees may be a third thing since it involves bad # code generation (not an ICE) even with the manually added 'volatile'. # # but the same old workaround works for this case, even if this feels a # bit like voodoo programming and may only be hiding the issue. # # Reported-and-tested-by: Sean Christopherson <seanjc@google.com> # Link:
