Bug ID: 64020
Summary: jit misses sin/cos optimizations
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
When running testsuite/jit.dg/test-functions.c under valgrind I noticed that
tree-ssa-math-opts.c:execute_cse_sincos_1 was bailing out at this conditional:
fndecl = mathfn_built_in (type, BUILT_IN_CEXPI);
if (!fndecl)
return false;
(which is actually a memory leak; I'll submit a fix for that as part of PR
jit/63854)
TODO: Why does this fail, and is this leading to missed optimizations in the
jitted code?
