# [PATCH] Explicitly truncate bswap operand to uint32_t 1 messages from 2009-10-29 to 2009-10-29. Participants: Benjamin Kramer. Thread: https://gitlist.dev/t/21423 ## Benjamin Kramer, 2009-10-29 17:43 Subject: [PATCH] Explicitly truncate bswap operand to uint32_t Message-ID: <4AE9D45A.9010805@googlemail.com> URL: https://gitlist.dev/e/4AE9D45A.9010805%40googlemail.com ``` There are some places in git where a long is passed to htonl/ntohl. llvm doesn't support matching operands of different bitwidths intentionally. This patch fixes the build with llvm-gcc (and clang) on x86_64.
