We had mistakenly believed that GCC's 'cc' referred to the entire condition-code register (cr0 through cr7) -- and implemented this in r205630 to fix PR19326, but 'cc' is actually an alias only to 'cr0'. This is causing LLVM to clobber too much with legacy code with inline asm using the 'cc' clobber. Fixes PR21451. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223328 91177308-0d34-0410-b5e6-96231b3b80d8
