[LLVMdev] Avoiding MCRegAliasIterator with register units
Jakob, I've implemented a patch that reworks the MCRegAliasIterator to dynamically compute the register aliases. The size reduction in the RegDiffLists are rather dramatic. Here are a few size differences for MCTargetDesc.o files (before and after) in bytes: R600 - 36160B - 11184B - 69% reduction ARM - 28480B - 8368B - 71% reduction Mips - 816B - 576B - 29% reduction One side effect of

Incorrect placement of an instruction after PostRAScheduler pass
Hi, I’m facing a crash issue (--target=arm-linux-gnueabi -march=armv8-a+crc -mfloat-abi=hard) and debugging the problem, I found that an intended branch was not taken due to bad code generation after the Post RA Scheduler pass. A CMPri instruction after an INLINEASM block (which inturn contains a cmp, bne instruction) is being moved before the INLINEASM block incorrectly resulting in two

Check sub register relations in RA
Hi there, In my register allocator, I was trying to get the parent of a register in ARM. That is: D0 <-> S0, S1. Given S0, how am I able to get D0?

[LLVMdev] Makefile.config
Hi John, I have attached my Makefile.config. I noticed that I did'nt have SRC_ROOT and OBJ_ROOT variables defined as such in my environment. But I noticed that this is defined in the Makefile.config by default to the same values. All the same, I tried defining both these variables in my .cshrc, but I still get the same error. The main directory for me is /home/llvm, and I have

[LLVMdev] Need help on SPEC 95 "standard" commandlines
Does anyone know the "standard" commandline to compile and run spec95 benchmarks ? I found some scripts in llvm test suite (External/SPEC/CINT95), but I am not sure if they are the *default ref* configurations. <Some of them seem to use smaller problem sizes.> SPEC95 was retired many years ago, so few people around me know how to compile and run them.

[LLVMdev] Need help on SPEC 95 "standard" commandlines
Some of the run commandlines don't seem to be the *default ref* configuration. For instance, in 099.go, what's in the script is: LEVEL = ../../../.. BM=099.go ifeq ($(RUN_TYPE),test) STDIN_FILENAME = /dev/null STDOUT_FILENAME = null.out RUN_OPTIONS = 40 19 else STDIN_FILENAME = 2stone9.in STDOUT_FILENAME = 2stone9.out RUN_OPTIONS = 50 9 endif include ../../Makefile.spec95

[LLVMdev] Registers and Register Units
You may have noticed Andy and me committing TableGen patches for "register units". I thought I'd better explain what they are. Some targets have instructions that operate on sequences of registers. I'll use ARM examples because it is the most notorious. ARM has, for example: vld1.64 {d1, d2}, [r0] The instruction loads two d-registers, but they must be consecutive. ARM also

[LLVMdev] Assert in LiveInterval update
Hi Jakob, I've got a good test case that I'm working on at the moment. I noticed something odd though: Is '0' a valid register unit? I'm seeing a LiveInterval with li->reg == 0 show up, which previously wasn't valid. We have a few checks around the place to disregard the '0' physreg - could these trigger on interaction with a '0' interval? That could

It sounds like the Makefiles are not creating the gccld command line correctly. Some questions: 1) Can you send us your Makefile.config? 2) Can you tell us
