[Bug bootstrap/25670] New: [4.2 Regression] build fail with 'make all-gcc'
I've configured with:
./configure --prefix=.../install --disable-nls --disable-libgcj
--enable-languages=c
Executed:
make all-gcc
Output:
...
make[2]: Leaving directory `.../intl'
cat: stage_last: No such file or directory
make: invalid option -- a
Usage: make [options] [target] ...
...
It appeared after: Revision 108512
I think the problem is the missing check for 'stage_last' file
in the Makefile.
The following modification solved the problem, but I didn't
test it very thoroughly.
Makefile.tpl:
-unstage = [ -f stage_current ] || $(MAKE) `cat stage_last`-start
+unstage = [ -f stage_current ] || if [ -f stage_last ]; then $(MAKE) `cat
stage_last`-start; fi

[Bug tree-optimization/22564] [4.1 Regression] Compilation time increased about 11%
--- Additional Comments From loki at gcc dot gnu dot org 2005-07-20 12:31 --- (In reply to comment #1) You are probably right, but it is hard to find such a test case, because there is only one significant daily regression (I guess from merging), but this one doesn't explain the overall change. IMHO the graphs suggest that the daily bugfixes increased the compilation time day after day. So, it's maybe difficult to clearly show which algorithms are responsible for this regression. Soever, I will search for some tests which will demonstarte this compile-time-hog. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22564
