Add injectivity annotations (#9500) (commit: 603506a)
Signal handling in native code without the page table (#9682)Signal handlers sometimes need to know whether the signal occurredin ocamlopt-generated code, as opposed to runtime or C library code.Today this determination uses a page table lookup to keep trackof dynamically-loaded modules, plus ad-hoc tests for the main program.This PR uses the code fragment table instead. That's more reliable,less ad-hoc, and independent of the page table.i386nt.asm: add caml_system__code_{begin,end}, ,like in the other ports. (commit: e4bf109)
