...s call to getFixupKindNumBytes() - which can return 1,2, 3, or 4 depending upon the FixupKind The code in ApplyFixup() seems to be lifted from the X86. AFAIK, the initial Fixup.Offset() is always divisible by 4, at least for ARM mode - i.e. it is always at the instruction boundary. it looks like adjustFixupValue() is meant to create a mask that can be bitwise OR'ed into the full instruction, which is 2 or 4 bytes So what does it mean to patch 1 or 3 bytes starting from the instruction boundary? I don't know enough about Macho to tell whether this is a bug or not. If it isn't, apologies for th...

Hi Everyone, I'm working Chromium targeting Windows on ARM64 platform. As a part of this work I ran into an issue related to llvm in Swiftshader. Currently fixup_aarch64_movw relocation type is not supported for COFF ARM64 (AArch64WinCOFFObjectWriter). As far as I see, Microsoft hasn't defined indicator for this relocation type. I haven't seen documented anywhere. For AArch32
