* | CodeGenPrep: preserve inbounds attribute when sinking GEPs. | Tim Northover | 2019-03-12 | 1 | -2/+2 |
| | | | | | | | | | Targets can potentially emit more efficient code if they know address computations never overflow. For example ILP32 code on AArch64 (which only has 64-bit address computation) can ignore the possibility of overflow with this extra information. llvm-svn: 355926 | ||||
* | [ARM, Thumb1] Prevent ARMTargetLowering::isLegalAddressingMode from ↵ | Evgeny Astigeevich | 2017-08-24 | 1 | -0/+45 |
accepting illegal modes ARMTargetLowering::isLegalAddressingMode can accept illegal addressing modes for the Thumb1 target. This causes generation of redundant code and affects performance. This fixes PR34106: https://bugs.llvm.org/show_bug.cgi?id=34106 Differential Revision: https://reviews.llvm.org/D36467 llvm-svn: 311649 |
