esp32s3: fix boot crash caused by LLVM 22 / lld l32r relocation bug#5533
Merged
Conversation
Replace movi instructions with constants outside the 12-bit signed range (-2048..2047) with movi+slli sequences. Large constants cause the assembler to emit auto-generated .literal section entries, which triggers an lld bug where l32r PC-relative offsets are miscalculated when .literal.* sections are merged with .text.* sections.

I need to merge because it is a critical bug in the current assembly code. |
