Merge branch 'ss/revert-builtin-bswap-stuff'

2025-06-13T20:29:14Z

Revert a botched bswap.h change that broke ntohll() functions on big-endian systems with __builtin_bswap32/64(). * ss/revert-builtin-bswap-stuff: Revert "bswap.h: add support for built-in bswap functions"

Revert "bswap.h: add support for built-in bswap functions"

2025-06-12T20:23:39Z

Since 6547d1c9 (bswap.h: add support for built-in bswap functions, 2025-04-23) tweaked the way the bswap32/64 macros are defined, on platforms with __builtin_bswap32/64 supported, the bswap32/64 macros are defined even on big endian platforms. However the rest of this file assumes that bswap32/64() are defined ONLY on little endian machines and uses that assumption to redefine ntohl/ntohll macros. The said commit broke t4014-format-patch.sh test, among many others on s390x. Revert the commit. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Junio C Hamano

compat: fixes for header handling with OpenBSD / NetBSD

2025-06-03T14:36:17Z

Handle OpenBSD and NetBSD as FreeBSD / DragonFly are. OpenBSD would need _XOPEN_SOURCE to be set to 700. Its simpler to just not set _XOPEN_SOURCE. CC strbuf.o strbuf.c:645:6: warning: call to undeclared function 'getdelim'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] r = getdelim(&sb->buf, &sb->alloc, term, fp); ^ 1 warning generated.

bswap.h: add support for built-in bswap functions

2025-04-23T15:53:04Z

Newer compiler versions, like GCC 10 and Clang 12, have built-in functions for bswap32 and bswap64. This comes in handy, for example, when targeting CLANGARM64 on Windows, which would not be supported without this logic. Signed-off-by: Dennis Ameling Signed-off-by: Junio C Hamano
