[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.

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

.L6:ble- 6,.L2
.L3:li 0,1
mr 3,0
blr
what decides which variant is chosen?
is it possible to force inlining?

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.

thats the same issue like the konqueror crash which I couldn't
find a workaround for in gcc either.

--- Additional Comments From pluto at pld-linux dot org 2005-03-25 12:37

(In reply to comment #3)
This looks like a bug in your installation of glibc.
#define INIT_SEGV \
do \
{ \
struct old_i386_kernel_sigaction kact; \
kact.k_sa_handler = catch_segv; \
kact.k_sa_mask = 0; \
kact.k_sa_flags = 0x400;\
kact.sa_restorer = restore; \
syscall (SYS_sigaction, SIGSEGV, kact, NULL); \
} \
while (0)
This works on a native 32bit compiler with a native 32bit glibc.
Can you confirm that this is your bug in your installation of glibc?
bits/syscall.h 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.

Now I'm trying rebuild gcc with added java, objc and fortran support
but install fails. It worked several snapshots ago, now it's broken.

I have no idea what is going on here but I will note that -O3
-fno-tree-dominator-opts works.
-O3 -fno-ivopts does not work
-O3 -fno-strict-aliasing does not work.
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 L219 can change state of startbuf.

I have a simple testcase:

@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0

@ lr needed for prologue
bx lr
-mthumb-interwork is disabled by default (vide man).
why gcc4 produces bx lr ? (gcc34 works fine).

[Bug rtl-optimization/18560] better optimalization of EOR/MOV block.
--- Additional Comments From pluto at pld-linux dot org 2005-02-11 10:47 --- (In reply to comment #4) The new register allocator (new-ra) has been removed because it was buggy and there were no plans to fix it. I was using it to show that the initial MOV was an unrelated issue. Your code snippet shows that the rotate and the EOR are being merged, which is what this PR was about. The PR is about initial eor/mov opt., not eor/rotate ;-) At this moment the comercial IAR compiler generates good code. The GCC should be good too :) reverse: 0x0D04 E0201860 EOR R1, R0, R0, ROR #16 0x0D08 E3C118FF BIC R1, R1, #0xFF 0x0D0C E1A01421 MOV R1, R1, LSR #8 0x0D10 E0210460 EOR R0, R1, R0, ROR #8 0x0D14 E12FFF1E BX LR -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18560

How did you configure gcc?
This works for me and many other people.
Even libgcj is not found also, this looks like a something is wrong with
your build.
libgcj.* exist in rpm's buildroot, libgij.a too but i can't see libgij.so.
This really sounds like your rpm being wrong, can you compile without using
rpm and see if libgij is
there?
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].
