Error compiling with cross-compiler

[ronwa...@gmail.com]

Hi all -

I'm attempting to compile for 64-bit windows from my linux, and am getting this:

x86_64-w64-mingw32-gcc -D FP_64BIT -D TFM_X86_64 -Wall -W -Wshadow -Isrc/headers -O3 -funroll-loops -fomit-frame-pointer   -c -o src/mont/fp_montgomery_reduce.o src/mont/fp_montgomery_reduce.c

/tmp/ccF312V4.s: Assembler messages:

/tmp/ccF312V4.s:95: Error: incorrect register `%r9d' used with `q' suffix

/tmp/ccF312V4.s:99: Error: operand type mismatch for `add'

/tmp/ccF312V4.s:102: Error: operand type mismatch for `movq'

/tmp/ccF312V4.s:105: Error: incorrect register `%r9d' used with `q' suffix

/tmp/ccF312V4.s:109: Error: operand type mismatch for `add'

(etc)

The other code up to there is fine.

I also ahve this problem compiling on Mac OS/X trying to do 32bit compile:

gcc-4.8 -m32 -DTFM_X86 -Wall -W -Wshadow -Isrc/headers -O3 -funroll-loops -fomit-frame-pointer   -c -o src/mul/fp_mul_comba.o src/mul/fp_mul_comba.c

src/mul/fp_mul_comba.c: In function 'fp_mul_comba':

src/mul/fp_mul_comba.c:50:1: error: 'asm' operand has impossible constraints

           MULADD(*tmpx++, *tmpy--);

           ^

src/mul/fp_mul_comba.c:50:1: error: 'asm' operand has impossible constraints

Any suggestions?

Hi,

please try out the updated version from github and tell me if that fixes your problem

It works great for the mingw, both 64 and 32 bit, thanks.

However, on OS/X I still get this problem when I do "CC='gcc-4.8 -m32' make -B"

Right; 64 bit is fine; my attempt with "-m32" is what failed.

And with tomcrypt and window 64:

(the tomsfastmath is the latest git, so is tomcrypt)

Yep; switching to develop seems to fix the problem, thanks!

which branch of tomcrypt do you use?
if you're using master - please try out develop

it seems to be the same issue as tfm had, but that has already been fixed

also you don't need the "-D FP_64BIT -D TFM_X86_64", that must be
automatically generated but that's less important

1. please read the rules and avoid top-posting
2. "-m32" is what I tested

Still the same, using the development code:

Please try again, I've pushed some changes I had locally and forgot to
publish.

But please be aware of https://github.com/libtom/tomsfastmath/issues/5
which affects the montgomery reduction...

Larry built a tool to verify that issue at
https://github.com/buggywhip/LibTom-TFM-scratch

Thanks.  My latest effort (after updating from git):

gcc-4.9 -Wall -W -Wshadow -Isrc/headers -m32 -O3 -funroll-loops -fomit-frame-pointer   -c -o src/mul/fp_mul_comba.o src/mul/fp_mul_comba.c
