Hi, Please review this 8u backport of JDK-8207057 which adds debug info when assembling assembler files. The build system changed between 9+ and 8u, so it's an independent patch from JDK 12's version.
Bug: https://bugs.openjdk.java.net/browse/JDK-8207057 webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8207057/jdk8/01/ Testing: Debugging of assembler files in gdb. Eyeballing compile logs. Thoughts? Thanks, Severin
