Bug ID: 38348
Summary: polly crashing with -O3 -ffast-math
Product: Polly
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Other
Assignee: polly-dev at googlegroups.com

Preprocessed source(s) by clang
Code works fine when following command is used to compile
"clang -O3 -ffast-math -c filename.c"
"clang -O3 -mllvm -polly filename.c"
but crashes on "clang -O3 -ffast-math -mllvm -polly filename.c"
I get following output in console.
clang-7:
/home/pankaj/Installations/llvm7.00/llvm/tools/polly/lib/CodeGen/IslExprBuilder.cpp:724:
llvm::Value* polly::IslExprBuilder::createId(isl_ast_expr*): Assertion
