Hi; I took a bunch of patches that were merged into the GCC 4.1 branch (under GPLv2) and prepared a patch for merging them into our base gcc. These are supposed to be bug fixes only. You can get the patch here: http://people.freebsd.org/~pfg/patches/patch-contrib-gcc And, for those really interested, the log is here: http://people.freebsd.org/~pfg/patches/gcc41-pr-log It may be my imagination but the patch seems to be causing more warnings than usual and it breaks the kernel here: ____ $ make cc -c -O2 -Os -pipe -fno-strict-aliasing -march=athlon64 -std=c99 -g -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -Wmissing-include-dirs -fdiagnostics-show-option -nostdinc -I. -I../../.. -I../../../contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-omit-frame-pointer -mcmodel=kernel -mno-red-zone -mno-mmx -mno-sse -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fstack-protector -Werror ../../../cam/scsi/scsi_sa.c cc1: warnings being treated as errors ../../../cam/scsi/scsi_sa.c: In function 'samount': ../../../cam/scsi/scsi_sa.c:1887: warning: 'comp_supported' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:1888: warning: 'write_protect' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:1887: warning: 'comp_enabled' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2728: warning: 'current_speed' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2728: note: 'current_speed' was declared here ../../../cam/scsi/scsi_sa.c:2727: warning: 'current_density' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2727: note: 'current_density' was declared here ../../../cam/scsi/scsi_sa.c:2725: warning: 'current_blocksize' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2725: note: 'current_blocksize' was declared here ../../../cam/scsi/scsi_sa.c:2728: warning: 'current_speed' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2728: note: 'current_speed' was declared here ../../../cam/scsi/scsi_sa.c:2725: warning: 'current_blocksize' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2725: note: 'current_blocksize' was declared here ../../../cam/scsi/scsi_sa.c:2728: warning: 'current_speed' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2728: note: 'current_speed' was declared here ../../../cam/scsi/scsi_sa.c:2725: warning: 'current_blocksize' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2725: note: 'current_blocksize' was declared here ../../../cam/scsi/scsi_sa.c:2728: warning: 'current_speed' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2728: note: 'current_speed' was declared here ../../../cam/scsi/scsi_sa.c:2725: warning: 'current_blocksize' may be used uninitialized in this function ../../../cam/scsi/scsi_sa.c:2725: note: 'current_blocksize' was declared here *** Error code 1 ... ____ Other stuff I tested (Apache OpenOffice) builds fine. cheers, Pedro.
