Hi, Since LLVM does not contain an assembler and linker to generate native code, do people have to write their own assembler if the target is different from the host? Or did I misunderstand something? Thanks. Xun Li ArchLab Department of Computer Science University of California, Santa Barbara

Hi, I was trying to use llc with soft-float option to generate soft-float code for Sparc. But it does not work. With or without -soft-float option will generate the same code for llc. Is this still an experimental feature? -- Xun Li Computer Architecture Lab Department of Computer Science University of California, Santa Barbara

The documentation is correct, and the observation that the IR verifier is currently not verifying this property is also correct. Due to the way that dbg.declares are handled by later stages, LLVM can only keep track of one dbg.declare per variable and that is intentional. The dbg.declare intrinsic is supposed to pin a variable to a stack slot, such as in the code that clang emits at -O0. If you

Hi, I have been trying to figure this out for a long time and really need some help. I am compiling C programs which uses some math functions (such as pow, ceil) into SPARC ISA, using llvm-gcc. I imagine below is the right process: llvm-gcc -c -emit-llvm *.c llvm-ld -lm *.bc -o test llc -march=sparc test.bc -o test.s However when I look into test.s, I realized that those math functions are not

Hi All, I am working on a custom defined architecture which implements Sparc ISA but without floating point instructions. I have two questions regarding using LLVM: 1. How to enable soft-float when building llvm-gcc? 2. How to let llvm-gcc generate native code (binaries) for Sparc? Do I have to compile glibc or newlib for Sparc and link with it together? I am kinda confused so it would be great
