Peter Collingbourne	78a1609fa2	s/tblgen/llvm-tblgen/g in a few missed places, including the tests ... llvm-svn: 141294	2011-10-06 13:39:59 +00:00
Jeffrey Yasskin	4927fd0032	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. llvm-svn: 99103	2010-03-20 23:08:45 +00:00
Dan Gohman	268cfea6bc	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. llvm-svn: 57663	2008-10-17 01:33:43 +00:00
Reid Spencer	4572ce85b0	Regression is gone, don't try to find it on clean target. ... llvm-svn: 33296	2007-01-17 07:59:14 +00:00
