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

...(s1) = G_ICMP intpred(sgt), %0(s32), %1     %5:_(s32) = G_SELECT %4(s1), %2, %3 On mips 32, integer compare uses i32 as result and that result is zero extended. For G_SELECT, we will select instructions that check whether "test register" was zero or not (selected instructions are movz or movn). Test register has size 32, having that in mind, idealy, legalizer should produce     %4:_(s32) = G_ICMP intpred(sgt), %0(s32), %1     %5:_(s32) = G_SELECT %4(s32), %2, %3 after combining all extends and truncs.

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 ldr r0, =...

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
