libgcrypt-1.9.0: 32 bit cross build fails on asm code

balducci
hello

(my specs are enclosed below)

just tried to cross-build  32 bit libgcrypt-1.9.0 on a 64 bit machine
and getting:

    ----8<----
    libtool: compile:  gcc -m32 -DHAVE_CONFIG_H -I. -I.. -I../src -I../src -I../mpi -I../mpi -I/usr/include -I/usr/Xorg/include -fvisibility=hidden -fno-delete-null-pointer-checks -Wall -c rijndael-aesni.c  -fPIC -DPIC -o .libs/rijndael-aesni.o
    rijndael-aesni.c: In function 'aesni_ocb_enc':
    rijndael-aesni.c:2815:7: error: 'asm' operand has impossible constraints
     2815 |       asm volatile ("pxor   %[tmpbuf0],%%xmm1\n\t"
          |       ^~~
    make[3]: *** [Makefile:1355: rijndael-aesni.lo] Error 1
    make[3]: Leaving directory '/home/balducci/tmp/install-us-d/libgcrypt-1.9.0.d/libgcrypt-1.9.0/cipher'
    ---->8----

No problem whatsoever building for native 64 bit.

I get the same error (always for the 32 bit cross build) on two
machines with different cpu's (both AMD, though)

32 bit build succeeds if I run with --disable-asm, but since it has worked
flawlessly for ages (without --disable-asm), I'm just wondering if asm is
not supported any longer for this cross build, or if 1.9.0 needs some
fix (or if I am missing something obvious, of course)

I haven't changed anything in my installation script (since 1.4.6).

thanks in advance for any hint/help
ciao

Hi!

thanks for the report.  I opened a ticket for this:
https://dev.gnupg.org/T5257
Please check over there for status updates.

(I accidently mentioned gnupg-users in the annoucement mail and not
 gcryypt-devel which would been the right one).


Shalom-Salam,

   Werner
