RE: Linker error

Turns out the Darwin linker does not like the jrcxz instruction for some reason.  Perhaps because it uses a 2 byte (length == 1) displacement?  The error message seemed to indicate only 4 byte displacements (length == 2) were valid.  

 

Replacing jrcxz with:

 

cmp $0, %rcx

je .LocalLabel

 

…fixes the problem.

 

It would seem the Darwin assembler and linker are not in sync.

I’m getting this error from the linker on Leopard:

 

ld: in intloop_darwin_x86_64.o, in section __TEXT,__text reloc 278: length != 2 and X86_64_RELOC_BRANCH not supported

 

Can someone please explain what I’m doing wrong?  This is being compiled/assembled/linked in 64 bit mode.

 

The file intloop_darwin_x86_64.o is generated by the assembler ‘as’.  Versions are below:

 

email@hidden:246 % as -v

Apple Computer, Inc. version cctools-667.3~21, GNU assembler version 1.38

 

email@hidden:250 % ld -v

@(#)PROGRAM:ld  PROJECT:ld64-77

 

 

 

Thanks,
