* Clean up PPC CPU capabilities and Montgomery code.jsing2024-11-012-1090/+2
| | | | | | | | | | ppc64-mont.pl (which produces bn_mul_mont_fpu64()) is unused on both powerpc and powerpc64, so remove it. ppccap.c doesn't actually contain anything to do with CPU capabilities - it just provides a bn_mul_mont() that calls bn_mul_mont_int() (which ppc-mont.pl generates). Change ppc-mont.pl to generate bn_mul_mont() directly and remove ppccap.c. ok tb@
* Replace uses of endbr64 with _CET_ENDBR from cet.htb2024-02-243-13/+13
| | | | | | | | | cet.h is needed for other platforms to emit the relevant .gnu.properties sections that are necessary for them to enable IBT. It also avoids issues with older toolchains on macOS that explode on encountering endbr64. based on a diff by kettenis ok beck kettenis

* Replace bn_sub_part_words() with bn_sub().jsing2023-02-221-210/+0
| | | | | | | | Now that bn_sub() handles word arrays with potentially different lengths, we no longer need bn_sub_part_words() - call bn_sub() instead. This allows us to entirely remove the unnecessarily complex bn_sub_part_words() code. ok tb@

* Use .section .rodata instead of a plain .rodatatb2023-02-091-1/+1
| | | | | | | | At least gcc 12 on Fedora is very unhappy about a plain .rodata and throws Error: unknown pseudo-op: `.rodata'. So add a .section in front of it to make it happy. ok deraadt miod

* Remove sparc related files from libcrypto.jsing2023-01-311-1458/+0

* Move {mul,sqr}_add_c{,2} macros from bn_asm.c to bn_local.h.jsing2023-01-201-1/+6
| | | | | | | | | | | These depend on other macros that are in already in bn_local.h and this makes them available to other source files. A lot more clean up will be needed in the future. Of course x86_64-gcc.c makes use of the same macro names - sprinkle some undef in there for the time being. ok tb@

* Make internal header file names consistenttb2022-11-261-2/+2
| | | | | | | | | | | | | | | | Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names used for internal headers. Move all these headers we inherited from OpenSSL to *_local.h, reserving the name *_internal.h for our own code. Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h. constant_time_locl.h is moved to constant_time.h since it's special. Adjust all .c files in libcrypto, libssl and regress. The diff is mechanical with the exception of tls13_quic.c, where #include <ssl_locl.h> was fixed manually. discussed with jsing, no objection bcook

* Replace all uses of magic numbers when operating on OPENSSL_ia32_P[] bymiod2016-11-044-12/+13
| | | | | | | | | | | | | | | meaningful constants in a private header file, so that reviewers can actually get a chance to figure out what the code is attempting to do without knowing all cpuid bits. While there, turn it from an array of two 32-bit ints into a properly aligned 64-bit int. Use of OPENSSL_ia32_P is now restricted to the assembler parts. C code will now always use OPENSSL_cpu_caps() and check for the proper bits in the whole 64-bit word it returns. i386 tests and ok jsing@

* Try to clean the maze of <openssl/bn.h> defines regarding the BN internals.miod2014-04-241-10/+0
| | | | | | | | | | | | | | | | | | | | | | | The intent of this change is to only keep support for two kind of architectures: - those with 32-bit int and long, and 64-bit long long, where ``long * long -> long long'' multiplication routines are available. - those with 64-bit int and long, and no 128-bit long long type. This gets rid of the SIXTY_FOUR_BIT_LONG, SIXTY_FOUR_BIT (not the same!), THIRTY_TWO_BIT, SIXTEEN_BIT and EIGHT_BIT defines. After this change, the types and defines are as follows: arch: 64bit 32bit rationale BN_LLONG undefined defined defined if l * l -> ll BN_ULLONG undefined u long long result of BN_LONG * BN_LONG BN_ULONG u long u int native register size BN_LONG long int the same, signed BN_BITS 128 64 size of 2*BN_ULONG in bits BN_BYTES 8 4 size of 2*BN_ULONG in bytes BN_BITS2 64 32 BN_BITS / 2 Tested on various 32-bit and 64-bit OpenBSD systems of various endianness.
