[MLton-user] Re: Mac OS X on Intel

[John Reppy]

I did the port of SML/NJ to the Intel Mac and the issues were mostly  
minor.

The calling convention issue is that MacOS X expects stack frames to  
be 16-byte
aligned and small structs (<= 8 bytes) are returned in registers.

The assembly code issues are in the psuedo-ops.  The Apple toolchain  
uses a
very old version of gas (dating back to the NeXT days), which doesn't
recognize some common directives.  Also, the Mach-O format has a  
different
section naming scheme.  The .text and .data directives will work, but  
anything
more complicated will have to be mapped to a different directive.
