Reid Kleckner	4a18a4e8c1	Don't promote byval pointer arguments when padding matters ... Don't promote byval pointer arguments when when their size in bits is not equal to their alloc size in bits. This can happen for x86_fp80, where the size in bits is 80 but the alloca size in bits in 128. Promoting these types can break passing unions of x86_fp80s and other types. Patch by Thomas Jablin!

Rafael Espindola	adb277286a	Remove tail marker when changing an argument to an alloca. ... Argument promotion can replace an argument of a call with an alloca. This requires clearing the tail marker as it is very likely that the callee is now using an alloca in the caller. This fixes pr14710. llvm-svn: 199909	2014-01-23 17:19:42 +00:00
