[LLVMdev] Standalone use of compiler-rt for ARM

[Taylor Trimble]

Hi all! This is my first mailing list, and first mailing list post all in one!

I’m trying to use the llvm compilers and other toolchain technologies to compile and link c code for the ARM Cortex-M3 microcontroller series. I am currently able to compile and link my own simplified source (like just a main function that returns zero and an add function), and can compile other sources given by my microcontroller’s vendor (NXP). However, NXP’s libraries generate code that requires the symbols __aeabi_uldivmod, __aeabi_malloc, and other optimized versions of common functionality.

These are for sure included with compiler-rt, but I haven’t figured out how to compile compiler-rt into a library I can link into my toolchain.

Do you guys have pointers? Thanks!

Taylor
