Source: ffcall
Severity: normal
Tags: patch
User: debian-powe...@lists.debian.org
Dear Maintainer,
The package ffcall fails to build from source on ppc64el because some
definitions
were missing for the platform.
I have created a patch, mostly copying powerpc64 .c and .s files and making
some changes
to *powerpc64le.s files to support ELFv2 (basically changing .opd section usage
by .localentry,
since the former is not in ELFv2 ABI).
Just removing the line that uses '.opd' section allows the package to build,
but I assumed
it needed an entry point definition, so I just changed it according to what can
be found on ELFv2
ABI specs at https://wiki.debian.org/ppc64el in ABI Documentation section.
I also added the entries to Makefile.in files. I could have used the same .c
files that are in use
for powerpc64, but I had rather copied them so there won't be any confusions.
The package still lacks dh-autoreconf usage so configure files are updated but
as it builds without
it and its mere addition causes the build to break, I prefered to do that in a
separate work.
I am not an expert on this subject, so I apologize in advance for any messing
up I could have
done with the patch. So please let me know if you have any comments.
Thanks and regards.
Fernando

++ !!! THIS ROUTINE MUST BE COMPILED gcc -O !!!
++
++ Foreign function interface for a 64-bit PowerPC with gcc
++
++ This calls a C function with an argument list built up using macros
++ defined in avcall.h.
++
++ PowerPC64 Argument Passing Conventions:
++
++ All arguments, except the first 8 words, are passed on the stack with
++ word alignment. The first 13 doubles and floats are also passed in
++ floating-point-registers.
++ To return a structure, the called function copies the value to space
++ pointed to by its first argument, and all other arguments are shifted
++ down by one.
++
++ The AIX argument passing conventions are used:
++ - the first 13 doubles and floats are passed in FP registers,
++ and when they do, there is still room allocated for them in the
++ argument sequence (integer regs or stack).
++ - Structures are passed in the argument sequence. But structures
++ containing floats or doubles are passed in FP registers?!
++
++ Compile this routine with gcc -O (or -O2 -fno-omit-frame-pointer or -g -O)
++ to get the right register variables. For other compilers use the
++ pre-compiled assembler version.
