Fun x86 encoding tricks: when adding an immediate value of 128, use a SUB instruction instead of an ADD, because -128 can be encoded in an 8-bit signed immediate field, while +128 can't be. This avoids the need for a 32-bit immediate field in this case. A similar optimization applies to 64-bit adds with 0x80000000, with the 32-bit signed immediate field. To support this, teach tablegen how to handle 64-bit constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57663 91177308-0d34-0410-b5e6-96231b3b80d8 2008-10-17 01:33:43 +00:00			`// RUN: tblgen %s \| grep -- 4294901760`
Add support for XFAILing valgrind runs with memory leak checking independently of runs without leak checking. We add -vg to the triple for non-checked runs, or -vg_leak for checked runs. Also use this to XFAIL the TableGen tests, since tablegen leaks like a sieve. This includes some valgrindArgs refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99103 91177308-0d34-0410-b5e6-96231b3b80d8 2010-03-20 23:08:45 +00:00			`// XFAIL: vg_leak`
