with clean tool and obj dirs, the tool gcc that I built does not look in
this directory, eg for <mmintrin.h> included by pixman-mmx.c on i386
a simple file containing only an include statement
% cat t.c
#include <mmintrin.h>
with a 5.99.41 userland,
% ktruss -i /usr/tools/bin/i486--netbsdelf-gcc -mmmx -c t.c | grep mmintrin
"#include <mmintrin.h>\n"
23537 1 cc1
__stat50("/usr/tools/bin/../lib/gcc/i486--netbsdelf/4.1.3/include/mmintrin.h.gch",
0xbfbfdfa0) Err#2 ENOENT
23537 1 cc1
open("/usr/tools/bin/../lib/gcc/i486--netbsdelf/4.1.3/include/mmintrin.h", 0x4,
0x1b6) Err#2 ENOENT
23537 1 cc1 __stat50("/usr/include/mmintrin.h.gch", 0xbfbfdfa0)
Err#2 ENOENT
23537 1 cc1 open("/usr/include/mmintrin.h", 0x4, 0x1b6) = 5
and it finds it naturally, but during a build.sh build with --sysroot,
% ktruss -i /usr/tools/bin/i486--netbsdelf-gcc -mmmx
--sysroot=/var/work/NetBSD-current/obj/destdir.i386 -c t.c | grep mmintrin
t.c:1:22: error: mmintrin.h: No such file or directory
"#include <mmintrin.h>\n"
27551 1 cc1
__stat50("/var/work/NetBSD-current/obj/destdir.i386/usr/include/mmintrin.h.gch",
0xbfbfdf70) Err#2 ENOENT
27551 1 cc1
open("/var/work/NetBSD-current/obj/destdir.i386/usr/include/mmintrin.h", 0x4,
0x1b6) Err#2 ENOENT
"mmintrin.h: No such file or directory"
it fails, yet the file
/var/work/NetBSD-current/obj/destdir.i386/usr/include/gcc-4.1/mmintrin.h
does exist..
