Update test: dynamic_stackalloc size must be rounded to ensure stack ptr be left in a valid state. llvm-svn: 41134 2007-08-16 23:51:28 +00:00			`; RUN: llvm-as < %s \| llc -march=x86 -mtriple=i686-apple-darwin \| grep and \| count 1`

It's not necessary to do rounding for alloca operations when the requested alignment is equal to the stack alignment. llvm-svn: 40004 2007-07-18 16:29:46 +00:00
