Thanks for the reply!
For clarification, the ultimate goal is to have a tcc cross-compiler for riscv32 (targeting the esp32c3 chip). This is for Charles Lohr's espwebc3 project:
https://github.com/cnlohr/espwebc3 I am developing on an Arch Linux machine. As I want cross-compiler support, I am trying to use the riscv newlib library as my C standard library (as supplied by the riscv64-elf-newlib package on Arch Linux
https://archlinux.org/packages/community/any/riscv64-elf-newlib/) which is the same library that the riscv-gcc cross-compiler uses for embedded targets (for both 32 and 64 bit riscv).
Right now, I was just trying to get the riscv64 cross compiler working (tested with QEMU, as I don't have a riscv64 system to play with). Then my goal would be to add riscv32 support to tcc.
I will try your suggestions for compiling later tonight and see if I can remove any definitions without breaking anything :-)
Thanks,
