The commands to reproduce the issues are in the commit messages. I tested on Super Mario Odyssey using [nx2elf](https://github.com/shuffle2/nx2elf) converted binaries and gdb-multiarch: ``` (gdb) monitor info Process: 0x51 (Application) Program Id: 0x0100000000010000 Layout: Alias: 0x1103400000 - 0x21033fffff Heap: 0x2103400000 - 0x23033fffff Aslr: 0x0008000000 - 0x7fffffffff Stack: 0x1083400000 - 0x11033fffff Modules: 0x0080b3d000 - 0x0080b40fff nnrtld 0x0080b41000 - 0x0081ff1fff RedStar.nss 0x0081ff2000 - 0x008270efff multimedia 0x008270f000 - 0x00833e2fff nnSdk (gdb) monitor mappings Mappings: 0x0000000000 - 0x0080b3cfff Free ----- [0, 0] 0x0080b3d000 - 0x0080b3efff r-x Code ----- [0, 0] 0x0080b3f000 - 0x0080b3ffff r-- Code ----- [0, 0] 0x0080b40000 - 0x0080b40fff rw- CodeData ----- [0, 0] 0x0080b41000 - 0x008156bfff r-x Code ----- [0, 0] 0x008156c000 - 0x0081cdafff r-- Code ----- [0, 0] 0x0081cdb000 - 0x0081ff1fff rw- CodeData ----- [0, 0] 0x0081ff2000 - 0x0082365fff r-x Code ----- [0, 0] 0x0082366000 - 0x00825c0fff r-- Code ----- [0, 0] 0x00825c1000 - 0x008270efff rw- CodeData ----- [0, 0] 0x008270f000 - 0x0082c3cfff r-x Code ----- [0, 0] 0x0082c3d000 - 0x00832bffff r-- Code ----- [0, 0] 0x00832c0000 - 0x00833e2fff rw- CodeData ----- [0, 0] 0x00833e3000 - 0x0083403fff Free ----- [0, 0] 0x0083404000 - 0x0083404fff rw- ThreadLocal ----- [0, 0] 0x0083405000 - 0x1083403fff Free ----- [0, 0] 0x1083404000 - 0x1083503fff rw- Stack ----- [0, 0] 0x1083504000 - 0x7fffffffff Free ----- [0, 0] (gdb) set sysroot (gdb) set solib-search-path /Users/duncan/Downloads/smo-program Reading symbols from /Users/duncan/Downloads/smo-program/rtld.elf...

[cmake] enable clang-cl and WoA builds (#348)

2025-09-09T18:47:49+00:00

Compilation and CMake fixes for both Windows on ARM and clang-cl, meaning Windows can now be built on both MSVC and clang on both amd64 and aarch64. Compiling on clang is *dramatically* faster so this should be useful for CI.

gdbstub_arch: Directly access SP register

2022-06-30T16:47:40+00:00

Currently to access the SP register, RegRead and RegWrite rely on a out-of-bounds array access to reach the next element in a struct. As of writing only git versions of GCC catch this error. Specify the SP register when we want to access it in these functions.
