RISC-V objcopy + variable fixes + ARM32 split header #106

wants to merge 6 commits into from

Commits on Sep 26, 2024

  1. ARM32 crt0: Split headers and code 

    I finally figured out how to best achieve this without breaking GNU ld

* Force code to be at known dest of 4096
* Move _start into .text
* Load the _start symbol address and then minus 4096 to get the load address

This should make the binary more PE32 compatible

Change in ncroxon/gnu-efi#45
