Sanjay Patel	5e7b7b7503	[x86] regenerate checks with update_llc_test_checks.py ... The dream of a unified check-line auto-generator for all phases of compilation is dead. The llc script has already diverged to be better at its goal, so having 2 scripts that do almost the same thing is just causing confusion. We can rip out the llc ability in update_test_checks.py next and rename it, so it will be clear that we have one script for llc check auto-generation and another for opt. llvm-svn: 305206	2017-06-12 17:31:36 +00:00
Sanjay Patel	904cd39b05	[x86] Allow merging multiple instances of an immediate within a basic block for code size savings, for 64-bit constants. ... This patch handles 64-bit constants which can be encoded as 32-bit immediates. It extends the functionality added by https://reviews.llvm.org/D11363 for 32-bit constants to 64-bit constants.
