Some dll/exe files end up having absolute path names embedded in them despite the use of `--disable-absolute-paths-in-output` build option. This option effectively translates into adding `-pathmap` to compilation lines, but doesn't (always) achieve the desired effects. The reason for that is in the use of Windows-style path for the argument provided to `pathmap`. The slash characters in the path passed as an argument get removed by the `fixpath` script that pre-processes all commands on Windows prior to running them and is supposed to convert Unix-style paths to what is understood by Windows.
For example: $ build/windows-x86_64-server-release/fixpath print -pathmap:C:\cygwin64\home\maxim\work\repr.build.1=s -pathmap:C:cygwin64homemaximworkrepr.build.1=s However, if a "normal" Unix-style path is provided, it gets converted correctly: $ build/windows-x86_64-server-release/fixpath print -pathmap:/home/maxim/work/repr.build.1=s -pathmap:C:\cygwin64\home\maxim\work\repr.build.1=s This commit changes the `-pathmap` compiler option to use "normal", Unix-style paths on Windows. Those will be changed to Windows style by the `fixpath` script. Verified by running two builds (details below) in different directories on the same machine; with this commit, all the exe/dll files under `.../images/jdk/...` are the same. Builds were produced by running the following commands on Windows 10 x64 with Visual Studio 2019 installed: ./configure --with-debug-level=release --with-jvm-features=shenandoahgc --with-version-pre= --with-version-build=1 --with-version-opt=b42 --with-toolchain-version=2019 --disable-ccache --enable-cds=yes --enable-reproducible-build --with-source-date=1643953637 --with-hotspot-build-time=2022-02-04 --with-copyright-year=2022 --disable-absolute-paths-in-output --with-boot-jdk=/home/maxim/work/zulu17.0.81-ea-jdk17.0.0-ea.35-win_x64 make reconfigure clean make images ------------- Commit messages: - 8281262: Windows builds in different directories are not fully reproducible Changes: https://git.openjdk.java.net/jdk/pull/7344/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7344&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8281262 Stats: 3 lines in 1 file changed: 0 ins; 2 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/7344.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7344/head:pull/7344 PR: https://git.openjdk.java.net/jdk/pull/7344
