Add option to emit @llvm.trap as a function call instead of a trap instruction. rdar://9249183. llvm-svn: 129107

; RUN: llc < %s -mtriple=arm-apple-darwin | FileCheck %s -check-prefix=INSTR
Change -arm-trap-func= into a non-arm specific option. Now Intrinsic::trap is lowered into a call to the specified trap function at sdisel time. llvm-svn: 129152
2011-04-09 05:37:21 +08:00
; RUN: llc < %s -mtriple=arm-apple-darwin -trap-func=_trap | FileCheck %s -check-prefix=FUNC
Make FastISel::SelectInstruction return before target specific fast-isel code handles Intrinsic::trap if TargetOptions::TrapFuncName is set. This fixes a bug in which the trap function was not taken into consideration when a program was compiled without optimization (at -O0). <rdar://problem/16291933> llvm-svn: 206323

This patch is to fix radar://8426430. It is about llvm support of __builtin_debugtrap() which is supposed to consistently raise SIGTRAP across all systems. In contrast, __builtin_trap() behave differently on different systems. e.g. it raises SIGTRAP on ARM, and SIGILL on X86. The purpose of __builtin_debugtrap() is to consistently provide "trap" functionality, in the mean time preserve the compatibility with on gcc on __builtin_trap(). The X86 backend is already able to handle debugtrap(). This patch is to: 1) make front-end recognize "__builtin_debugtrap()" (emboddied in the one-line change to Clang). 2) In DAG legalization phase, by default, "debugtrap" will be replaced with "trap", which make the __builtin_debugtrap() "available" to all existing ports without the hassle of changing their code. 3) If trap-function is specified (via -trap-func=xyz to llc), both __builtin_debugtrap() and __builtin_trap() will be expanded into the function call of the specified trap function. This behavior may need change in the future. The provided testing-case is to make sure 2) and 3) are working for ARM port, and we already have a testing case for x86. llvm-svn: 166300
