Changes
Summary
- [ARM] Remove non-existent cpu arm1176j-s and use mpcore for v6k The ARMTargetParser.def contains an entry for arm1176j-s which is the default for the ArmV6K architecture. This cpu does not exist, there are only arm1176jz-s and arm1176jzf-s and they are both architecture ArmV6KZ. The only CPUs that are actually ArmV6K are the mpcore, mpcore_nofpu and later revisions of the arm1136 family r1px (which we don't have a table entry for). This patch removes the arm1176j-s and makes mpcore the default for armv6k. Differential Revision: https://reviews.llvm.org/D52594
- [ARM] Allow execute only code on Cortex-m23 The NoMovt feature prevents the use of MOVW/MOVT instructions on Cortex-M23 for performance reasons. These instructions are required for execute only code so NoMovt should be disabled when that option is enabled. Differential Revision: https://reviews.llvm.org/D52551
- Remove extra whitespace. NFC. (test commit)
- [ARM][v8.5A] Add speculation barriers SSBB and PSSBB This adds two new barrier instructions which can be used to restrict speculative execution of load instructions. Patch by Pablo Barrio! Differential revision: https://reviews.llvm.org/D52484
