2012-10-23[ms-inline asm] When parsing inline assembly we set the base register to aChad Rosier
non-zero value as we don't know the actual value at this point. This is necessary to get the matching correct in some cases. However, the actual value set as the base register doesn't matter, since we're just matching not emitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166523 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-19This patch is to fix radar://8426430. It is about llvm support of ↵Shuxin Yang
__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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166300 91177308-0d34-0410-b5e6-96231b3b80d8
