Rafael Espindola	74ec8fabec	Convert test to FileCheck. ... llvm-svn: 210049	2014-06-02 21:23:54 +00:00
Chandler Carruth	8a358b3669	Convert all tests using TCL-style quoting to use shell-style quoting. ... This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s llvm-svn: 159525	2012-07-02 12:47:22 +00:00
Dan Gohman	795e3db7ce	Code that checks WillNotOverflowSignedAdd before creating an Add ... can safely use the NSW bit on the Add. llvm-svn: 85164	2009-10-26 22:14:22 +00:00
Dan Gohman	205b641954	Change tests from "opt %s" to "opt < %s" so that opt doesn't see the ... input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537	2009-09-11 18:01:28 +00:00
Dan Gohman	c95df8b6d8	Use opt -S instead of piping bitcode output through llvm-dis. ... llvm-svn: 81257	2009-09-08 22:34:10 +00:00
Dan Gohman	8d84372836	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. llvm-svn: 81226	2009-09-08 16:50:01 +00:00
Chris Lattner	b387fd90fc	Teach instcombine 4 new xforms: ... (add (sext x), cst) --> (sext (add x, cst')) (add (sext x), (sext y)) --> (sext (add int x, y)) (add double (sitofp x), fpcst) --> (sitofp (add int x, intcst)) (add double (sitofp x), (sitofp y)) --> (sitofp (add int x, y)) This generally reduces conversions. For example MiBench/telecomm-gsm gets these simplifications: HACK2: %tmp67.i142.i.i = sext i16 %tmp6.i141.i.i to i32 ; <i32> [#uses=1] %tmp23.i139.i.i = sext i16 %tmp2.i138.i.i to i32 ; <i32> [#uses=1] %tmp8.i143.i.i = add i32 %tmp67.i142.i.i, %tmp23.i139.i.i ; <i32> [#uses=3] HACK2: %tmp67.i121.i.i = sext i16 %tmp6.i120.i.i to i32 ; <i32> [#uses=1] %tmp23.i118.i.i = sext i16 %tmp2.i117.i.i to i32 ; <i32> [#uses=1] %tmp8.i122.i.i = add i32 %tmp67.i121.i.i, %tmp23.i118.i.i ; <i32> [#uses=3] HACK2: %tmp67.i.i190.i = sext i16 %tmp6.i.i189.i to i32 ; <i32> [#uses=1] %tmp23.i.i187.i = sext i16 %tmp2.i.i186.i to i32 ; <i32> [#uses=1] %tmp8.i.i191.i = add i32 %tmp67.i.i190.i, %tmp23.i.i187.i ; <i32> [#uses=3] HACK2: %tmp67.i173.i.i.i = sext i16 %tmp6.i172.i.i.i to i32 ; <i32> [#uses=1] %tmp23.i170.i.i.i = sext i16 %tmp2.i169.i.i.i to i32 ; <i32> [#uses=1] %tmp8.i174.i.i.i = add i32 %tmp67.i173.i.i.i, %tmp23.i170.i.i.i ; <i32> [#uses=3] HACK2: %tmp67.i152.i.i.i = sext i16 %tmp6.i151.i.i.i to i32 ; <i32> [#uses=1] %tmp23.i149.i.i.i = sext i16 %tmp2.i148.i.i.i to i32 ; <i32> [#uses=1] %tmp8.i153.i.i.i = add i32 %tmp67.i152.i.i.i, %tmp23.i149.i.i.i ; <i32> [#uses=3] HACK2: %tmp67.i.i.i.i = sext i16 %tmp6.i.i.i.i to i32 ; <i32> [#uses=1] %tmp23.i.i5.i.i = sext i16 %tmp2.i.i.i.i to i32 ; <i32> [#uses=1] %tmp8.i.i7.i.i = add i32 %tmp67.i.i.i.i, %tmp23.i.i5.i.i ; <i32> [#uses=3] This also fixes a bug in ComputeNumSignBits handling select and makes it more aggressive with and/or. llvm-svn: 51302	2008-05-20 05:46:13 +00:00
