From: "jakub at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/30506] not sibcalling a function Date: Thu, 11 Mar 2010 12:34:00 -0000 [thread overview] Message-ID: <20100311123404.31197.qmail@sourceware.org> (raw) In-Reply-To: <bug-30506-7667@http.gcc.gnu.org/bugzilla/> ------- Comment #6 from jakub at gcc dot gnu dot org 2010-03-11 12:34 ------- That's not a bug. Unlike x86-64, on i?86 when calling (or jumping to) a PLT slot in position independent code %ebx must be set to the calling function's PIC pointer. As %ebx is call saved register, this precludes sibcall. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30506
