[Bug other/21398] New: gcc emits invalid operands for xchgb %b0, %h0
the code like this:
unsigned short swap16(unsigned short x)
{
asm volatile ("xchgb %b0, %h0" : "=q" (x) : "0" (x));
return x;
}
produces:
swap16: xchgb %dil, %di <== %di isn't valid high 8-bit form.
movzwl %di, %eax
ret
IIRC the %rdi, %rsi, %rsp, %rbp haven't a high 8-bit form.

[Bug other/21237] New: unnecessary __cmpdi2 usage?
in function cryptcompress_truncate() from reiserfs4 patch
compiler uses __cmpdi2 for old_size vs new_size (64 bit) comparision:
result = (old_size < new_size ? cryptcompress_append_hole(inode, new_size) :
prune_cryptcompress(inode, new_size, update_sd, aidx));
in another case for simple foo() method gcc inlines __cmpdi2 equivalent:
int foo(long long x, long long y) { return (x < y); }
foo:cmpw 7,5,3
li 0,0
bgt- 7,.L3
cmplw 6,6,4
beq- 7,.L6
.L2:mr 3,0
blr
.L6:ble- 6,.L2
.L3:li 0,1
mr 3,0
blr
what decides which variant is chosen?
is it possible to force inlining?

[3] STLport-4.6.2 (used by openoffice-1.1.3)
OpenOffice's open-file dialog closes immediately after it was launched.
This behavior came with rebuilded STLport.
It works fine with gcc-3.4, 3.3 and some earlier 4.0-snaps.
I will do a bsearch in free time.

please ignore previous post.
gcc passes params in the right way but something is wrong.
with the original sourcecode gdb shows stack frame with
invalid parameters (name, xmluiFile):
#4 0x4008b10c in KonqMainWindow (this=0x812afc0, [EMAIL PROTECTED],
openInitialURL=false, name=0x2e ,
[EMAIL PROTECTED]) at konq_mainwindow.cc:218
if I access xmluiFile at the begin of this cstr, eg.
qDebug("name=%p, xmlui=%s", name, xmluiFile.ascii());
gdb will show a stack frame with correct params:
#4 0x4008b130 in KonqMainWindow (this=0x812afc0, [EMAIL PROTECTED],
openInitialURL=false, name=0x0, [EMAIL PROTECTED])
at konq_mainwindow.cc:218
disassembler shows only s/eax/edx/ in several places.
is this a gdb-6.3 bug?
i give up.

from i386 defines SYS_sigaction.
x86_64 doesn't define SYS_sigaction (even for -m32 abi).
it looks like a bug in dual arch glibc headers.

[Bug other/20426] error: initializer element is not constant

I think that relinking java libs with `-rpath /usr/lib` are quite wrong. At build/install time java libs exist only in rpm/BUILD/gcc-4.0-20050305/obj-i686-pld-linux/i686-pld-linux/libjava/.libs and $(DESTDIR)/$libdir.

I've looked into final tree-dump and found something interesting.
In the source we can find a [2] strcpy(startbuf, ...)
which can change the state of startbuf between [1] and [3].
if (usestart) {
[1]if (*startbuf == '\0' &&
zp->z_format != NULL &&
strchr(zp->z_format, '%') == NULL &&
strchr(zp->z_format, '/') == NULL)
[2] (void) strcpy(startbuf, zp->z_format);
eat(zp->z_filename, zp->z_linenum);
[3]if (*startbuf == '\0')
error(_("can't determine time zone abbreviation to use
just after until time"));
else
addtt(starttime,
addtype(startoff, startbuf,
startoff != zp->z_gmtoff,
startttisstd,
startttisgmt));
}
Diff shows that the optimizer assumed D.10077=startbuf[0] incorrectly
as const because can change state of startbuf.

[Bug regression/19935] New: unexpected "bx lr" in arm mode.
I have a simple testcase:
void test()
{
}
# arm-linux-gcc test.c -S -O2 produces:
test:
@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
@ lr needed for prologue
mov pc, lr
# arm-linux-gcc test.c -S -O2 -mcpu=arm7tdmi-s produces:
test:
@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
@ lr needed for prologue
bx lr
-mthumb-interwork is disabled by default (vide man).
why gcc4 produces "bx lr" ? (gcc34 works fine).

rpm just calls:
%{__make} -C obj-%{_target_platform} \
profiledbootstrap \
GCJFLAGS="%{rpmcflags}" \
BOOT_CFLAGS="%{rpmcflags}" \
STAGE1_CFLAGS="%{rpmcflags}" \
LDFLAGS_FOR_TARGET="%{rpmldflags}" \
mandir=%{_mandir} \
infodir=%{_infodir}
%{__make} install \
mandir=%{_mandir} \
infodir=%{_infodir} \
DESTDIR=$RPM_BUILD_ROOT
and doesn't do anything else.
should i call something more than `make profiledbootstrap` ?

[Bug rtl-optimization/18560] New: better optimalization of EOR/MOV block.
/*
This function reverses the bytes in a word. The method was discovered in
1986 following a competition between ARM programmers; it requires just 4
instructions and 1 work register. A method using only 3 instructions per
word reversed was also found, but it has some set-up overhead and uses
a 2nd register.
*/
unsigned long reverse(unsigned long v)
{
unsigned long t;
t = v ^ ((v << 16) | (v >> 16));// EOR r1,r0,r0,ROR #16[1]
t &= ~0xff; // BIC r1,r1,#&ff
v = (v << 24) | (v >> 8); // MOV r0,r0,ROR #8
return v ^ (t >> 8);// EOR r0,r0,r1,LSR #8
}
The gcc-3.4.3 with -O2 produces:
reverse:
mov r3, r0 [2]
mov r0, r0, ror #16 [2]
eor r0, r0, r3 [2]
bic r0, r0, #16711680
mov r3, r3, ror #8
eor r0, r3, r0, lsr #8
mov pc, lr
Itc doesn't seem to produce [2] optimal code [1].
