After the VTA merge (i.e. as of rev. 151322, bootstrap on i386-pc-solaris2.10
fails since all? object files miscompare between stages 2 and 3. To
investigate
this, I've rebuild stage2 and stage3 plugin.o with -save-temps. The two .s
files
differ by additional .debug_* sections in stage3, together with many labels
(which shouldn't affect the object files), .loc statements. This accounts for
a significant size difference between the .o files:
-rw-r--r-- 1 ro gcc 32480 Sep 2 15:18 stage1-gcc/plugin.o
-rw-r--r-- 1 ro gcc 9936 Sep 2 16:29 stage2-gcc/plugin.o
-rw-r--r-- 1 ro gcc 35852 Sep 2 16:29 stage3-gcc/plugin.o
The stage2 plugin.o was built with

I'm attaching the .i and both .s files for further investigation.
sparc-sun-solaris2.11 bootstrap just broke in the same way.
