Adrian Prantl 3c6c14d14b ASAN: Provide reliable debug info for local variables at -O0. ... The function stack poisioner conditionally stores local variables either in an alloca or in malloc'ated memory, which has the unfortunate side-effect, that the actual address of the variable is only materialized when the variable is accessed, which means that those variables are mostly invisible to the debugger even when compiling without optimizations. This patch stores the address of the local stack base into an alloca, which can be referred to by the debug info and is available throughout the function. This adds one extra pointer-sized alloca to each stack frame (but mem2reg can optimize it away again when optimizations are enabled, yielding roughly the same debug info quality as before in optimized code). rdar://problem/30433661 Differential Revision: https://reviews.llvm.org/D41034 llvm-svn: 320415		2017-12-11 20:43:21 +00:00
