2014-08-29mpi: Re-indent longlong.h.Werner Koch1-249/+264
-- Indenting the cpp statements should make longlong.h better readable.
2013-12-04mpi: add inline assembly for x86-64Jussi Kivilinna1-0/+63
* mpi/longlong.h [__x86_64] (add_ssaaaa, sub_ddmmss, umul_ppmm) (udiv_qrnnd, count_leading_zeros, count_trailing_zeros): New. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-12-03Add aarch64 (arm64) mpi assemblyJussi Kivilinna1-0/+38
* mpi/aarch64/mpi-asm-defs.h: New. * mpi/aarch64/mpih-add1.S: New. * mpi/aarch64/mpih-mul1.S: New. * mpi/aarch64/mpih-mul2.S: New. * mpi/aarch64/mpih-mul3.S: New. * mpi/aarch64/mpih-sub1.S: New. * mpi/config.links [host=aarch64-*-*]: Add configguration for aarch64 assembly. * mpi/longlong.h [__aarch64__] (add_ssaaaa, sub_ddmmss, umul_ppmm) (count_leading_zeros): New. -- Add preliminary aarch64 assembly implementations for mpi. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-11-29Fix armv3 compile errorVladimir 'φ-coder/phcoder' Serbinenko1-1/+1
* mpi/longlong.h [__arm__ && __ARM_ARCH < 4] (umul_ppmm): Use __AND_CLOBBER_CC instead of __CLOBBER_CC. -- ARMv3 code uses __CLOBBER_CC at the end of clobber list while it should have been __AND_CLOBBER_CC. [jk: add changelog, rebase on libgcrypt repository] Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-11-29longlong.h on mips with clangVladimir 'φ-coder/phcoder' Serbinenko1-1/+2
* mpi/longlong.h [__mips__]: Use C-language version with clang. -- clang doesn't recognise =l / =h assembly operand specifiers but apparently handles C version well. [jk: add changelog, rebase on libgcrypt repository, reformat changed line so it does not go over 80 characters] Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-10-22mpi: allow building with clang on ARMJussi Kivilinna1-14/+13
* mpi/longlong.h [__arm__] (add_ssaaaa, sub_ddmmss, umul_ppmm) (count_leading_zeros): Do not cast assembly output arguments. [__arm__] (umul_ppmm): Remove the extra '%' ahead of assembly comment. [_ARM_ARCH >= 4] (umul_ppmm): Use correct inputs and outputs instead of registers. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-10-02Fix errors when building with Clang on PPCDmitry Eremin-Solenikov1-20/+20
* mpi/longlong.h (add_ssaaaa, sub_ddmmss, count_leading_zeros, umul_ppmm): Do not cast asm output to USItype. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>
2013-09-26Make libgcrypt build with Clang on i386Jussi Kivilinna1-8/+8
* cipher/longlong.h [__i386__] (add_ssaaaa, sub_ddmmss) (umul_ppmm, udiv_qrnnd): Do not cast asm output to USItype. -- Clang defines __GNUC__ even when it's not GCC compatible. As result Clang enables GCC-only assembly code in mpi/longlong.h and fails to build. However, since changes to make libgcrypt build with Clang are smallish, and changes do not cause problems with GCC, patch just does them. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-07-10Fix i386/amd64 inline assembly "cc" clobbersJussi Kivilinna1-6/+11
* cipher/bithelp.h [__GNUC__, __i386__] (rol, ror): add "cc" globber for inline assembly. * cipher/cast5.c [__GNUC__, __i386__] (rol): Ditto. * random/rndhw.c [USE_DRNG] (rdrand_long): Ditto. * src/hmac256.c [__GNUC__, __i386__] (ror): Ditto. * mpi/longlong.c [__i386__] (add_ssaaaa, sub_ddmmss, umul_ppmm) (udiv_qrnnd, count_leading_zeros, count_trailing_zeros): Ditto. -- These assembly snippets modify cflags but do not mark "cc" clobber. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-07-10mpi: Add __ARM_ARCH for older GCCJussi Kivilinna1-7/+26
* mpi/longlong.h [__arm__]: Construct __ARM_ARCH if not provided by compiler. -- GCC 4.8 defines __ARM_ARCH which provides forward compatible way to detect ARM architecture. Use this when available and construct otherwise. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-07-10mpi: add missing "cc" clobber for ARM assemblyJussi Kivilinna1-3/+3
* mpi/longlong.h [__arm__] (add_ssaaaa, sub_ddmmss): Add __CLOBBER_CC. [__arm__][__ARM_ARCH <= 3] (umul_ppmm): Ditto. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-07-10Tweak ARM inline assembly for mpiJussi Kivilinna1-4/+16
mpi/longlong.h [__arm__]: Enable inline assembly if __thumb2__ is defined. [__arm__]: Use __ARCH_ARM when defined. [__arm__] [__ARM_ARCH >= 5] (count_leading_zeros): New. -- Current ARM Linux distributions use EABI that enables thumb2, and therefore inline assembly is disable (because !defined(__thumb__) selector). However thumb2 allows the use of assembly instructions that longlong.h contains for ARM. So this patch enables inline assembly for ARM when __thumb2__ is defined in addition to __thumb__. Patch also adds optimization for count_leading_zeros() macro for ARM.

Debian. Taken from gnupg-1.3. * longlong.h: Added PowerPC 64 bit code from GPM-4.1.2 but didn't enable it yet. Some whitespace changes in HPPA to fix assembler problems on HP-UX.
