4 Subject: [PATCH] buildinfo: strip sysroot and debug-prefix-map from compiler
7 Content-Type: text/plain; charset=UTF-8
8 Content-Transfer-Encoding: 8bit
10 The openssl build system generates buildinf.h containing the full
11 compiler command line used to compile objects. This breaks
12 reproducibility, as the compile command is baked into libcrypto, where
13 it is used when running `openssl version -f`.
15 Add stripped build variables for the compiler and cflags lines, and use
16 those when generating buildinfo.h.
18 This is based on a similar patch for older openssl versions:

25 Update to fix buildpaths qa issue for '-fmacro-prefix-map'.
