Hal Finkel	84b0b8cc3b	[PowerPC] 'cc' should be an alias only to 'cr0' ... 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. llvm-svn: 223328	2014-12-04 00:46:20 +00:00
Hal Finkel	e63f5074c7	[PowerPC] Add a full condition code register to make the "cc" clobber work ... gcc inline asm supports specifying "cc" as a clobber of all condition registers. Add just enough modeling of the full register to make this work. Fixed PR19326. llvm-svn: 205630	2014-04-04 15:15:57 +00:00
