The following build error occurs with todays cvs main:
stage1/xgcc -Bstage1/ -B/opt/gnu64/hppa64-hp-hpux11.11/bin/ -c -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -fno-common -DHAVE_CONFIG_H -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include ../../gcc/gcc/regclass.c -o regclass.o
../../gcc/gcc/regclass.c: In function `allocate_reg_info':
../../gcc/gcc/regclass.c:2270: internal compiler error: in simplify_subreg, at simplify-rtx.c:2248
The following patch introduced the error:
2003-01-15 Roger Sayle <roger@eyesopen.com>
* gcse.c (one_cprop_pass): Change function arguments to take both
cprop_jumps and bypass_jumps flags instead of just alter_jumps.
(gcse_main): Update calls to one_cprop_pass, disabling bypassing.
(bypass_jumps): New function to perform separate jump bypassing pass.
* rtl.h (bypass_jumps): Add function prototype.
* timevar.def (TV_BYPASS): New timing variable.
* toplev.c (enum dump_file_index): Add new entry DFI_bypass.
(dump_file): New entry for the bypass RTL dump file.
(rest_of_compilation): Insert new jump bypassing optimization
pass after loop.
* doc/passes.texi: Document new pass.
The error doesn't occur under hppa-unknown-linux-gnu. So, it somehow
seems 64-bit related.
