Visoiu Mistrih Francis	514686acfd	[RISCV] Add correct Uses, Defs, isReturn to Zcmp (#81039) ... * they all do stack adjustments, so they all use and def x2. * popret and popretz also return * popretz also defines x10 This adds that to the TD file and updates the PushPopOptimizer to preserve the extra implicit operands added during frame lowering when converting to popret(z).	2024-02-07 14:30:45 -08:00
Craig Topper	4162a9bca4	[RISCV] Cleanup pass initialization. ... Remove redundant initializations from pass constructors that were already being initialized by LLVMInitializeRISCVTarget().	2023-12-07 18:21:38 -08:00
Craig Topper	44d4f975e4	[RISCV] Replace RISCV -> RISC-V in comments. NFC ... I did this once previously, but more uses have crept in.	2023-10-21 10:52:24 -07:00
Alex Bradbury	fc654b4f59	[RISCV][NFC] Correct/clarify RISCVPushPopOptimizer.cpp header comment ... Refer to Zcmp rather than Zca. Also, this pass will only modify POP instructions (replacing with POPRET if possible).	2023-10-10 16:50:15 +01:00
Anmol P. Paralkar	53e89f5e3f	[RISCV] Add bounds check before use on returned iterator. ... Check iterator validity before use; fixes a crash seen in the RISC-V Zcmp Push/Pop optimization pass when compiling an internal benchmark.

Alex Bradbury	cde5e4281b	[RISCV][NFC] Get rid of additional unneeded static_cast around RISCVSubtarget ... Some similar cases to 60152f1983336e709.	2023-07-20 14:37:58 +01:00
WuXinlong	c0221e006d	[RISCV] Add a pass to combine cm.pop and ret insts ... `RISCVPushPopOptimizer.cpp` combine `cm.pop` and `ret` to generates `cm.popretz` or `cm.popret` . Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D150416	2023-07-07 14:04:11 +08:00
