Hello Severin,
From looking at your jdk-submit job I can already say that it's not
working on Solaris:

jib > file.s...
I think we need to introduce a separate ASFLAGS_DEBUG_SYMBOLS variable
for this to work.

Hi,
Could I please get a review of this build fix? The problem is that no
debug info gets ever generated for assembler files in hotspot. The
proposed fix is to generated debug info via CFLAGS_DEBUG_SYMBOLS if so
requested. For example --with-native-debug-info=none no debug info is
generated. --with-native-debug-info=internal generates it. The question
is whether the assembler will accept the same debug-info related flags
as the compiler on all supported platforms (CFLAGS_DEBUG_SYMBOLS).
Thoughts?
Bug: https://bugs.openjdk.java.net/browse/JDK-8207057
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8207057/webrev.01/
Testing:
- I've manually verified via gdb that relevant debug info is present.
- Currently running this through jdk-submit
Thanks,
Severin
