However, when I try to assemble for AIX/PowerPC64 with this command: powerpc-ibm-aix53-as -a64 -u -o ../../rtl/units/powerpc64-aix/ctypes.o ../../rtl/units/powerpc64-aix/ctypes.s -mpwr5 Then I get the following error: Assembler messages: Fatal error: selected target format 'aixcoff64-rs6000' unknownThere is a discrepancy between bfd and gas. Try to configure for powerpc-ibm-aix or hack gas/config/tc-ppc.c
I had to hack gas/config/tc-ppc.c (manually add a "#define TE_AIX5"; it seems this should normally be set by gas/config/te-aix5.h, but this file doesn't appear to be included anywhere), because configuring for powerpc-ibm-aix resulted in linker errors:
powerpc-ibm-aix-ld -bpT:0x10000000 -bpD:0x20000000 -btextro -binitfini:P.BUG_.._main:FPC_LIB_EXIT -G -L. -o shr_64.o link.res -b64 -bE:linksyms.fpc
/Data/dev/aix/aixroot/lib/crt0_64.o: file not recognized: File format not recognized (that's a crt0_64.o from an AIX 5.3 machine).
Configuring that way also meant that ar's -X64_32 option was not supported (presumably such support was only added in AIX 5.x).
In any case, with the hack it does work. Thanks! Jonas PS: shall I file a bug report?
