5c028081 - [polly] Introduce -polly-print-* passes to replace -analyze.

Mon, 14 Mar 2022 13:39:25 +0000

[polly] Introduce -polly-print-* passes to replace -analyze.The `opt -analyze` option only works with the legacy pass manager and might be removed in the future, as explained in llvm.org/PR53733. This patch introduced -polly-print-* passes that print what the pass would print with the `-analyze` option and replaces all uses of `-analyze` in the regression tests.There are two exceptions: `CodeGen\single_loop_param_less_equal.ll` and `CodeGen\loop_with_condition_nested.ll` use `-analyze on the `-loops` pass which is not part of Polly.Reviewed By: aeubanksDifferential Revision: https://reviews.llvm.org/D120782 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll

965edde6 - Separate more constant factors of parameters

Sun, 14 Feb 2016 22:30:56 +0000

Separate more constant factors of parameters So far we separated constant factors from multiplications, however, only when they are at the outermost level of a parameter SCEV. Now, we also separate constant factors from the parameter SCEV if the outermost expression is a SCEVAddRecExpr. With the changes to the SCEVAffinator we can now improve the extractConstantFactor(...) function at will without worrying about any other code part. Thus, if needed we can implement a more comprehensive extractConstantFactor(...) function that will traverse the SCEV instead of looking only at the outermost level. Four test cases were affected. One did not change much and the other three were simplified.llvm-svn: 260859 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll

f4ee371e - tests: Drop -polly-detect-unprofitable and -polly-no-early-exit

Tue, 06 Oct 2015 15:36:44 +0000

tests: Drop -polly-detect-unprofitable and -polly-no-early-exitThese flags are now always passed to all tests and need to be disabled ifnot needed. Disabling these flags, rather than passing them to almost alltests, significantly simplfies our RUN: lines.llvm-svn: 249422 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll

173ecab7 - Remove target triples from test cases

Tue, 21 Apr 2015 14:28:02 +0000

Remove target triples from test casesI just learned that target triples prevent test cases to be run on otherarchitectures. Polly test cases are until now sufficiently target independentto not require any target triples. Hence, we drop them.llvm-svn: 235384 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll

d1e33e70 - ScopDetection: Only detect scops that have at least one read and one write

Thu, 19 Feb 2015 05:31:07 +0000

ScopDetection: Only detect scops that have at least one read and one writeScops that only read seem generally uninteresting and scops that only write aremost likely initializations where there is also little to optimize. To notwaste compile time we bail early.Differential Revision: http://reviews.llvm.org/D7735llvm-svn: 229820 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll

e42ddb9a - ScopInfo: Split start value from SCEVAddRecExpr to enable parameter sharing.

Mon, 05 Aug 2013 15:14:15 +0000

ScopInfo: Split start value from SCEVAddRecExpr to enable parameter sharing.SCoP invariant parameters with the different start value would deter parametersharing. For example, when compiling the following C code: void foo(float *input) { for (long j = 0; j < 8; j++) { // SCoP begin for (long i = 0; i < 8; i++) { float x = input[j * 64 + i + 1]; input[j * 64 + i] = x * x; } } }Polly would creat two parameters for these memory accesses: p_0: {0,+,256} p_2: {4,+,256} [j * 64 + i + 1] => MemRef_input[o0] : 4o0 = p_1 + 4i0 [j * 64 + i] => MemRef_input[o0] : 4o0 = p_0 + 4i0These parameters only differ from start value. To enable parameter sharing,we split the start value from SCEVAddRecExpr, so they would share a singleparameter that always has zero start value: p0: {0,+,256}<%for.cond1.preheader> [j * 64 + i + 1] => MemRef_input[o0] : 4o0 = 4 + p_1 + 4i0 [j * 64 + i] => MemRef_input[o0] : 4o0 = p_0 + 4i0Such translation can make the polly-dependence much faster.Contributed-by: Star Tan llvm-svn: 187728 List of files: /llvm-project-15.0.7/polly/test/ScopInfo/constant_start_integer.ll
