RISC-V support for LLVM projects (LLVM, Clang, ...)
Could we add something like `-mattr=+m,-div` or `-mattr=+mul` to generate multiplication instructions but not division (and remainder, etc.) instructions? I'm not the only one who wants this. For instance:
Currently the last part of `07-initial-codegen.mkd` render on github preview is messy. This trivial PR fixes this.
Hi everyone, I am trying to build a JIT for the RISC-V platform, but I could not figure out how. Could you provide some hints? Great thanks! Initially, I found...
As documented [here](https://gcc.gnu.org/onlinedocs/gcc/Machine-Constraints.html).
When using the llvm compiler for RISC-V E mode, there is no support. wish there could be some support on this format for future usage. Is there any plan on...
Now I’m doing something about rve. it seems like rve is not supported in llvm upstream. How can I add the rve to the LLVM backend? I have try to...
Based on the status of [patch D46822](https://reviews.llvm.org/D46822) -- which appears to be accepted, closed, and committed to upstream as of July 31, 2018 -- is this step under [How can...
Hello, I've managed to build the tool, but when running clang in the last step, I get a "/path/to/riscv64-unknown-elf/lib/crt0.o: error adding symbols: file in wrong format" error. Does anyone have...
Hi, Recently I ran the coremark on HiFive1 board, https://www.sifive.com/products/hifive1/ With GCC, my test result is 2.66, the official data is 2.73. They are very close. With LLVM built from...
Currently the code generation seems to optimize away everything but the no-throw code path. What's needed for generating code for the rest of the IR code paths? (e.g. landingpad, etc.)....
