[Bug rtl-optimization/32280] _mm_srli_si128, heinous code for some shifts
--- Comment #2 from ubizjak at gmail dot com 2007-06-11 07:35 ---
This is the fault of combine pass. It isn't obvious to me, why it is
converting:
(insn 7 6 13 2 shift.c:6 (set (subreg:TI (reg:V2DI 62) 0)
(ashift:TI (subreg:TI (reg:V2DI 61 [ __a ]) 0)
(const_int 64 [0x40]))) 1115 {sse2_ashlti3} (insn_list:REG_DEP_TRUE
6 (nil))
(expr_list:REG_DEAD (reg:V2DI 61 [ __a ])
(expr_list:REG_EQUAL (ashift:TI (subreg:TI (reg/v:V2DI 60 [ __a ]) 0)
(const_int 64 [0x40]))
(nil
)
to
(insn 7 6 13 2 shift.c:6 (parallel [
(set (subreg:TI (reg:V2DI 62) 0)
(ashift:TI (reg:TI 21 xmm0 [ __a ])

(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_DEAD (reg:V2DI 21 xmm0 [ __a ])
(nil
Note the clobber in above pattern. So, what is wrong with:
(define_insn sse2_ashlti3
[(set (match_operand:TI 0 register_operand =x)
(ashift:TI (match_operand:TI 1 register_operand 0)
(match_operand:SI 2 const_0_to_255_mul_8_operand n)))]

[Bug rtl-optimization/32283] New: Missed induction variable optimization
Consider the following code snippet
static volatile short a[(2048)];
short foo (int len, int v)
{
int i;
for (i = 0; i len; i++) {
a[i] = v;
}
return a[0];
}
This should generate a post_inc for accessing elements of a. The problem seems
to be in the loop optimizer that fails to identify 'i' as an induction
variable. For e.g the dump from 141r.loop2_invariant shows
(insn 16 15 75 4 (set (reg/v:SI 103 [ i ])
(const_int 0 [0x0])) 161 {*arm_movsi_insn} (nil))
(insn 75 16 17 4 (set (reg/f:SI 118)
(symbol_ref:SI (^a) [flags 0x2] var_decl 0xb7dc1000 a)) -1 (nil))
(code_label 17 75 18 5 4 [0 uses])
(note 18 17 21 5 [bb 5] NOTE_INSN_BASIC_BLOCK)
(insn 21 18 23 5 (set (reg:SI 110)
(ashift:SI (reg/v:SI 103 [ i ])
(const_int 1 [0x1]))) 115 {*arm_shiftsi3} (nil))
(insn 23 21 25 5 (set (mem/s/v:HI (plus:SI (reg:SI 110)
(reg/f:SI 118)) [3 a S2 A16])
(subreg/s/u:HI (reg:SI 102 [ pretmp.21 ]) 0)) 171 {*movhi_insn_arch4}
(nil))
(insn 25 23 26 5 (set (reg/v:SI 103 [ i ])
(plus:SI (reg/v:SI 103 [ i ])
(const_int 1 [0x1]))) 4 {*arm_addsi3} (nil))
(insn 26 25 27 5 (set (reg:CC 24 cc)
(compare:CC (reg/v:SI 106 [ len ])
(reg/v:SI 103 [ i ]))) 214 {*arm_cmpsi_insn} (nil))
(jump_insn 27 26 82 5 (set (pc)
(if_then_else (gt (reg:CC 24 cc)
(const_int 0 [0x0]))
(label_ref:SI 82)
(pc))) 224 {*arm_cond_branch} (expr_list:REG_BR_PROB (const_int
9900 [0x26ac])
(nil)))
Here reg 103 i.e 'i' is incremented by 1 always and therefore 110 always
increases by 2 which means that in each iteration the address in INSN 23 is 2
more than what it was in the previous iteration. If the access is converted
into something like
*118 = v
118 += 2,
then the auto-inc-dec pass will be able to convert this into a post_inc

[Bug libstdc++/32284] empty std::string w/ _GLIBCXX_FULLY_DYNAMIC_STRING faults
--- Comment #2 from pcarlini at suse dot de 2007-06-11 15:25 --- Hi Benjamin. If you ask me, this issue is INVALID: it is *not* supported building the library normally and then passing -D_GLIBCXX_FULLY_DYNAMIC_STRING on the command line, and never was! Simply because basic_string is exported, used in exported bits of locale, you know what I mean... As usual in such cases (e.g., changing locale model), the user has to configure with --enable-fully-dynamic-string and rebuild. In fact, note that the macro in the patch has the conditional wrapped in #ifndef _GLIBCXX_FULLY_DYNAMIC_STRING, code which at some point was supposed to make a difference only when a *normal* string was involved (in fact it doesn't, and that's why I removed it, the check is redundant): the fact that adding back that code avoids the segmentation fault is only because, by chance, this particular combination of exported normal string + inline fully dynamic string works apparently better, but nobody knows what would happen in other much more complex situations... That said, if you really feel strongly about adding back that conditional, it's up to you, but I would suggest at least adding a clear comment, summarizing the above. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32284

is miscompiled at -O1 -m32 or -O2 -m32.
This was fixed in 4.2 and on the trunk with PR25505 changes (the tree-nrv.c
change most importantly), NRV in this case is really a wrong thing to do,
as target is _Complex at virtual-outgoing-regs, but those are also used
for the call. Furthermore GCC then incorrectly computes where the region
actually was:
(insn 26 25 27 2 (set (mem/i:DF (plus:SI (reg/f:SI 56 virtual-outgoing-args)

(const_int 4 [0x4])))
]) -1 (nil)
(expr_list:REG_EH_REGION (const_int 0 [0x0])

(nil))
(insn 30 29 31 2 (parallel [

]) -1 (nil)
(nil))
(insn 31 30 32 2 (set (reg:DF 70)
(mem/c/i:DF (plus:SI (reg/f:SI 54 virtual-stack-vars)

(insn 32 31 33 2 (set (mem:DF (plus:SI (reg/f:SI 56 virtual-outgoing-args)

So, it stores the return value to %esp (== %ebp - 68 at that point) and
loads from %ebp - 40.

[Bug c++/32291] New: -Wformat either too picky or not picky enough
Compiling the following snippet with -Wformat (or -Wall) causes the compiler to
complain: wformat-bug.C:8: warning: format '%u' expects type 'unsigned int',
but argument 2 has type 'uint32_t'
The problem seems to be that stdint.h defines uint32_t as long in cygwin. I
realize that int != long on some platforms, but i686 isn't one of them. Why
should the user be forced to cast their uint32_t (read: 32-bit unsigned int) to
unsigned int before passing it to printf() when they are logically identical?
On the other hand, there's no complaint about passing a signed integer into an
unsigned format or vice-versa, even though the output value might actually
change because of the oversight in those cases.
wformat.C:
===
#include cstdio
#include stdint.h
int main() {
uint32_t a = ~0;
unsigned int b = a;
uint32_t c = b;
printf(%u\n, c); // warning (?)
int d = c;
unsigned e = d;
printf(%d\n, e); // no warning
printf(%u\n, d); // no warning
}
