re PR tree-optimization/63464 (compare one character to many: faster)
PR tree-optimization/63464
* gimple.h (gimple_seq_discard): New prototype.
* gimple.c: Include stringpool.h and tree-ssanames.h.
(gimple_seq_discard): New function.
* optabs.h (lshift_cheap_p): New prototype.
* optabs.c (lshift_cheap_p): New function, moved from...
* tree-switch-conversion.c (lshift_cheap_p): ... here.
* tree-ssa-reassoc.c: Include gimplify.h and optabs.h.
(reassoc_branch_fixups): New variable.
(update_range_test): Add otherrangep and seq arguments.
Unshare exp. If otherrange is NULL, use for other ranges
array of pointers pointed by otherrangep instead.
Emit seq before gimplified statements for tem.
(optimize_range_tests_diff): Adjust update_range_test
caller.
(optimize_range_tests_xor): Likewise. Fix up comment.
(extract_bit_test_mask, optimize_range_tests_to_bit_test): New
functions.
(optimize_range_tests): Adjust update_range_test caller.
Call optimize_range_tests_to_bit_test.
(branch_fixup): New function.
(execute_reassoc): Call branch_fixup.
* gcc.dg/torture/pr63464.c: New test.
* gcc.dg/tree-ssa/reassoc-37.c: New test.
* gcc.dg/tree-ssa/reassoc-38.c: New test.
