I am currently trying to compile a pretty simple program to work on an experimental board. It contains an (FPGA-version of) an ARMv4 processor. So basically, I try this (on my Ubuntu 18.04.1 LTS): clang -v --target=arm-none-eabi -c barehello.c -o barehelloCLANG.o clang -v --target=arm-none-eabi -c io.c -o io.o clang -v --target=arm-none-eabi barehelloCLANG.o io.o -o helloCLANGstatic -static

Hello, I am developing GlobalISel for MIPS. I have a few questions and observations about defining legality of generic instruction and also possible combining of instructions and artifacts in pre/post legalizer combiner or elsewhere (e.g. in some sort of instruction-select patterns). I look at legality as "If generic instruction can be selected into machine instruction, it is legal".

I am trying to add support for select_cc. In ARM it can be implemented with: mov $dst, $falseVal cmp $a, $b moveq $dst, $trueVal My current strategy is to expand select_cc in two ARM nodes: ARM::SELECT and ARM::CMP. The two nodes would be connected by a flag edge. ARM::CMP would then expand to "cmp $a, $b". This instruction has no results. It only alters the CPSR (current program

Both armasm and gnu as support an ldr pseudo instruction for loading constants that lowers to either a mov, movn, or a pc-relative ldr from the constant pool. It would be great if the llvm integrated assembler could support this feature as well. For example, using gnu as to compile this code: .text foo: ldr r0, =0x1 ldr r0, =-0x1 ldr r0, =0x1000001 ldr r0, =bar

Hello, Edmund, > Is it, or should it be legal for a Flag output to be used as input by > more than one other node? It's illegal. Multiple uses of the flag output do not make any sense, this breaks the semantics of flag operands. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University
