X-Mailer: bug 3.3.4
Delivered-To: submit@bugs.debian.org
Package: gcc
Version: 1:2.95.2-14
Severity: wishlist
Here are a couple of things I noticed for i386 while trying to fix alpha
unaligned traps.
1. Combining neighbouring instructions:
-- source --
#include <time.h>
#include <sys/time.h>
char *p;
void b(struct timeval);
void a() {
struct timeval k;
#if 0
memcpy(&k, p, sizeof(k));
b(k);
#else
b(*(struct timeval *)p);
#endif
}
-- assembly (gcc -O2 -S) --
.file "b.c"
.version "01.01"
gcc2_compiled.:
.comm p,4,4
.text
.align 4
.globl a
.type a,@function
a:
pushl %ebp
movl %esp,%ebp
subl $8,%esp
addl $-8,%esp
movl p,%eax
movl (%eax),%edx
movl 4(%eax),%ecx
pushl %ecx
pushl %edx
call b
leave
ret
.Lfe1:
.size a,.Lfe1-a
.ident "GCC: (GNU) 2.95.2 20000220 (Debian GNU/Linux)"
-- end --
The subl and the addl can be combined.
2. Removing unused local variables.
-- source --
#include <time.h>
#include <sys/time.h>
char *p;
void b(struct timeval);
void a() {
struct timeval k;
#if 1
memcpy(&k, p, sizeof(k));
b(k);
#else
b(*(struct timeval *)p);
#endif
}
-- assembly (gcc -O2 -S) --
.file "a.c"
.version "01.01"
gcc2_compiled.:
.text
.align 4
.globl a
.type a,@function
a:
pushl %ebp
movl %esp,%ebp
subl $24,%esp
movl p,%eax
movl (%eax),%edx
movl %edx,-8(%ebp)
movl 4(%eax),%eax
movl %eax,-4(%ebp)
addl $-8,%esp
movl -8(%ebp),%eax
movl -4(%ebp),%edx
pushl %edx
pushl %eax
call b
leave
ret
.Lfe1:
.size a,.Lfe1-a
.comm p,4,4
.ident "GCC: (GNU) 2.95.2 20000220 (Debian GNU/Linux)"
-- end --
I'm not sure how hard this is to do, but storing k and retrieving it again
seems to be a waste.

Changes:
gcc-4.0 (4.0.1-1) unstable; urgency=high
.
* GCC 4.0.1 final release. See /usr/share/doc/gcc-4.0/NEWS.{gcc,html}.
* Build fastjar on mips/mipsel, fix fastjar build without building java.
* Disable the comparision check on unstable/ia64. adaint.o differs,
currently cannot be reproduced with glibc-2.3.5 and binutils-2.16.1.
* libffi/hppa: Fix handling of 3 and 5-7 byte struct returns.
* amd64: Fix libgcc symlinks to point to /usr/lib32, instead of /lib32.
* On powerpc, don't build with -j >1, apparently doesn't succeeds
on the Debian buildd.
* Apply revised patch to make -mieee the default on alpha-linux,
and add -mieee-disable switch to turn the default off (Tyson Whitehead).
* Disable multiarch-includes; redo biarch-includes to include the paths
for the non-default biarch, when called with -m32/-m64.
* Move new java headers from libstdc++-dev to libgcj-dev, add replaces
line.
* Update classpath patch to work with cairo-0.5.1. Patch provided by
Michael Koch.
* Further classpath updates for gnu.xml and javax.swing.text.html.
Patch provided by Michael Koch.
* Require binutils (>= 2.16.1) as a build dependency and a dependency.
* On i386, require amd64-libs-dev (>= 1.2).
* Update debian/NEWS.{html,gcc}.
.
* Closing bug reports reported against older gcc versions (some of them
still present in Debian, but not anymore as the default compiler).
Usually, forwarded bug reports are linked to
http://gcc.gnu.org/PR<upstream bug number>
The upstream bug number usually can be found in the Debian reports.
