Rafael Espindola	47731fe3f1	Add support for passing variables declared to use a xmm register to asm ... statements using the "x" constraint. llvm-svn: 122679	2011-01-02 03:59:13 +00:00
Rafael Espindola	c56f847a96	Add support for declaring register contraints in variables. They are only used ... in asm statements: register int foo asm("rdi"); asm("..." : ... "r" (foo) ... We also only accept these variables if the constraint in the asm statement is "r". This fixes most of PR3933. llvm-svn: 122643	2010-12-30 22:59:32 +00:00
