Hi Ian Thanks for reply. Is it possible to override alloc to do the same thing as expand_buitlin_alloca in application codes? On Mon, 2009-07-13 at 14:17 -0700, Ian Lance Taylor wrote: > Janboe Ye writes: > > > normally gcc will use expand_builtin_alloca to handle variable ar

how to use expand_builtin_alloca

2009-07-13 Thread Janboe Ye
Hi, normally gcc will use expand_builtin_alloca to handle variable array. But mudflap will force this function to return immediately to invoke alloca explicit. Is there some way to still use expand_builtin_alloca without changing gcc source code? Thanks a lot! Janboe Ye
