Yeah, I'm it's supposed to not get inlined, but I think it does anyways. Atleast that's what I can see from looking at both asm files. They are here: http://www.prism.gatech.edu/~gtg277i/src/ The compile output is like this (this is how I made both files(but one has -O2 also)): # i686-pc-linux-gnu-gcc -S -D_BSD_SOURCE -Demacs -DHAVE_CONFIG_H -DUSE_GTK -I. -I/var/tmp/portage/emacs-cvs-22.0.50/work/emacs/src -D_BSD_SOURCE -DXTHREADS -D_REENTRANT -DXUSE_MTSAFE_API -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/freetype2/config -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -Wall xterm.c xterm.c: In function `XTread_socket': xterm.c:6951: warning: unused variable `event' xterm.c:7070: warning: label `out' defined but not used xterm.c: In function `x_calc_absolute_position': xterm.c:8124: warning: unused variable `win_x' xterm.c:8124: warning: unused variable `win_y' xterm.c: In function `x_iconify_frame': xterm.c:8767: warning: unused variable `result' xterm.c: In function `x_free_frame_resources': xterm.c:8893: warning: unused variable `bar' xterm.c:8894: warning: unused variable `b' xterm.c: In function `x_term_init': xterm.c:10106: warning: unused variable `atom' xterm.c: At top level: xterm.c:7621: warning: 'x_fatal_error_signal' defined but not used basically, O2 is like: x_error_handler: .LFB170: .loc 1 7745 0 pushl %ebp .LCFI497: movl %esp, %ebp .LCFI498: subl $664, %esp .LCFI499: movl %esi, -8(%ebp) .LCFI500: movl 8(%ebp), %esi movl %edi, -4(%ebp) .LCFI501: movl 12(%ebp), %edi movl %ebx, -12(%ebp) .LCFI502: .loc 1 7746 0 movl x_error_message_string, %eax cmpl Qnil, %eax je .L2330 .LBB530: .LBB531: .loc 1 7467 0 movl $200, %edx andl $-8, %eax movl %edx, 12(%esp) movl 12(%eax), %eax movl %eax, 8(%esp) movzbl 16(%edi), %eax movl %esi, (%esp) movl %eax, 4(%esp) call XGetErrorText and without it: x_error_handler: .LFB126: .loc 1 7745 0 pushl %ebp .LCFI345: movl %esp, %ebp .LCFI346: subl $8, %esp .LCFI347: .loc 1 7746 0 movl x_error_message_string, %eax cmpl Qnil, %eax je .L1130 .loc 1 7747 0 movl 12(%ebp), %eax movl %eax, 4(%esp) movl 8(%ebp), %eax movl %eax, (%esp) call x_error_catcher jmp .L1131 .L1130: .loc 1 7749 0 movl 12(%ebp), %eax movl %eax, 4(%esp) movl 8(%ebp), %eax movl %eax, (%esp) call x_error_quitter .L1131: .loc 1 7750 0 movl $0, %eax .loc 1 7751 0 leave ret .LFE126: .size x_error_handler, .-x_error_handler .section .rodata .align 4 .LC15: # gcc --version gcc (GCC) 3.4.3-20050110 (Gentoo Linux 3.4.3.20050110-r2, ssp-3.4.3.20050110-0, pie-8.7.7) Copyright (C) 2004 Free Software Foundation, Inc.
