FYI: Add native ecj support
Andrew John Hughes
gnu_andrew at member.fsf.org
Fri Sep 26 19:27:36 PDT 2008
This patch causes ecj to be built as a native binary
and used by javac in place of java and ecj.jar if GCJ
is found by configure. This speeds up the build quite
a bit, especially when compared with building with gij
or similar.
I also cleaned up a number of configure messages and
added ones which were missing.
Committed to IcedTea7.
ChangeLog:
2008-09-27 Andrew John Hughes <gnu_andrew at member.fsf.org>
* Makefile.am:
Build native ecj if GCJ is available.
* acinclude.m4:
Cleanup macros.
* configure.ac:
Cleanup macros and check for GCJ.
* javac.in:
Use native-ecj binary when available.
