Binutils fork with support for the ESP32 ULP co-processor
Using version 2.35_20220830 from esp-idf 5.1, `MOVE Rx, Ry` is apparently assembled as: ``` (MSB) 1110000100000000000000000yyyyxx ``` i.e. Rsrc2 is equal to Rsrc1, as if it was `MOVE Rx, Rx,...
This adds the BFD_RELOC_32 relocation to esp32 and esp32s2. Tested with both. This allows you to use the address of a label as a number, such as: ``` .data important:...
typecast error in make process: libbfd.h:268:4: error: cast between incompatible function types from ‘bfd_boolean (*)(bfd *)’ {aka ‘int (*)(bfd *)’} to ‘bfd_boolean (*)(bfd *, bfd *)’ {aka ‘int (*)(bfd *,...
### Overview For JUMP instructions using an absolute/constant symbol as an argument, binutils-esp32ulp produces a different output depending on whether that symbol is exported with `.global` or not. This appears...
This issue relates to how relative offsets specified as immediate values are handled after my recent PR (#18). After my recent PR (#18) was merged - thank you btw -...
the build fails on FreeBSD. the following is an excerpt of the build log. when looking for the `BFD_RELOC_ESP32S2ULP_GOT17M4` in the source, cannot find it in other files. my dumb...

Hi Of course this issue appears only on large assembly programs A JUMP instruction with absolute adress beyond 01FF will generate this error: Error: rel too far BFD_RELOC_16 I beleive...
