When trying to build 2.6.24-rc2 with checking by sparse 0.4, my "make" run dies with: CHECK kernel/sched.c kernel/sched.c:3616:15: warning: incorrect type in assignment (different signedness) kernel/sched.c:3616:15: expected long *switch_count kernel/sched.c:3616:15: got unsigned long *<noident> kernel/sched.c:3638:16: warning: incorrect type in assignment (different signedness) kernel/sched.c:3638:16: expected long *switch_count kernel/sched.c:3638:16: got unsigned long *<noident> sparse: flow.c:805: rewrite_parent_branch: Assertion `changed' failed. /bin/sh: line 1: 31460 Aborted /home/ts/kernel/sparse-0.4/sparse -D__linux__ -Dlinux -D__STDC__ -Dunix -D__unix__ -Wbitwise -Wno-decl -Wno-shadow -D__i386__ -nostdinc -isystem /usr/lib/gcc/i586-suse-linux/4.2.1/include -Wp,-MD,kernel/.sched.o.d -nostdinc -isystem /usr/lib/gcc/i586-suse-linux/4.2.1/include -D__KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Os -pipe -msoft-float -mregparm=3 -freg-struct-return -mpreferred-stack-boundary=2 -march=i686 -mtune=pentium4 -ffreestanding -maccumulate-outgoing-args -DCONFIG_AS_CFI=1 -DCONFIG_AS_CFI_SIGNAL_FRAME=1 -Iinclude/asm-x86/mach-default -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -fno-stack-protector -Wdeclaration-after-statement -Wno-pointer-sign -fno-omit-frame-pointer -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(sched)" -D"KBUILD_MODNAME=KBUILD_STR(sched)" kernel/sched.c make[1]: *** [kernel/sched.o] Error 134 make: *** [kernel] Error 2 make: *** Waiting for unfinished jobs.... I don't quite know what to make of this. It looks like a bug in sparse, but kernel/sched.c is perhaps not quite innocent either. Also it doesn't seem right that the entire kernel compilation aborts just because of a failed sparse run. Opinions?
