The patch titled i386: remove -maccumulate-outgoing-args has been removed from the -mm tree. Its filename was i386-remove-maccumulate-outgoing-args.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: i386: remove -maccumulate-outgoing-args From: Adrian Bunk <bunk@xxxxxxxxx> Contrary to the comment "newer gccs do it by default", newer gcc versions default to -maccumulate-outgoing-args only with CONFIG_CC_OPTIMIZE_FOR_SIZE=n, and then only with some CPU settings. Measured with an i386 defconfig, gcc 4.2.1 and kernel 2.6.23-rc1 ("orig" is the plain kernel, "changed is with -maccumulate-outgoing-args removed): $ ls -la vmlinux* -rwxrwxr-x 1 bunk bunk 6269713 2007-07-24 22:19 vmlinux.changed -rwxrwxr-x 1 bunk bunk 6425361 2007-07-24 22:19 vmlinux.orig $ size vmlinux.* text data bss dec hex filename 4493465 504108 614400 5611973 55a1c5 vmlinux.changed 4646160 504108 614400 5764668 57f63c vmlinux.orig $ That's a 2.5% size increase that does for sure hurt small systems. If the stack unwinder ever comes back and needs this as indicated in the comment, adding it to the cflags when the user enabled the unwinder should be a better option.
