Product: gcc

The reproducer is a bit too big, but it's the best I was able to achieve with
Creduce, Cvise, and manual reduction. UBSan and ASan say that it is compliant
with the standard.
Reproducer:
#include <stdio.h>
unsigned long long a;
void b(unsigned long long *f, int p2) { *f ^= p2; }
long c;
char e, i;
short g, m;
long long ab[1][25][21][22];
unsigned long long aa[1][21][22];
unsigned long long ae[1][25][21][21];
long long ac[129360];
char ad[25][1][21];
char ah[1][25][1][21];
short af[100];
long max(long f, unsigned long p2) { return f < p2 ? p2 : f; }
const int &max2(const int &f, const int &p2) { return f < p2 ? p2 : f; }
void foo(unsigned f, unsigned p2, char l, char p4, long long n[][25][21][22],
unsigned long long p6[][21][22], unsigned long long u[][25][21][21]) {
long an;
for (int j = 0; j < 4; j = p2)
for (short k = 0; k < 7; k += 2)
for (short o = 0; o < (short)p2 + 21742; o = l) {
for (signed char p = 2; p < 9; p += p4)
if (p6[j][o][p])
for (long q(3); 4 ? n[0][k][o][0] : 0;
q += p6[0][o][0] ? p6[j][0][p] : 0)
ac[j + q] = 5066799590;
for (long r(p4 - 16); r < 21; r += 4) {
ad[k][o][r] = max(u[j][k][o][r], f + u[j][k][o][r]);
long d = u[j][k][o][r];
an = d < p2 ? p2 : d;
e = ah[j][k][o][r] = an;
af[o * r] = i;
}
for (short s(c); s < (short)p2; s = 2)
for (short am(m); am; am = max2(3, p2))
for (long y = 0; y; y = 3)

Note "-O3 -g0 -fno-tree-vrp -fno-tree-ccp -fno-ivopts -fno-thread-jumps
-fno-tree-dominator-opts -fno-tree-vectorize" still fails but adding -fwrapv
allows it to pass.
Confirmed.

This is due to the peephole2 added in r12-2640-gf7bf03cf69cc:
;; Eliminate a reg-reg mov by inverting the condition of a cmov (#2).
;; mov r2,r3; mov r0,r1; dec r0; cmov r0,r2 -> dec r1; mov r0,r3; cmov r0, r1
(define_peephole2
[(set (match_operand:SWI248 2 "general_reg_operand")
(match_operand:SWI248 3 "general_gr_operand"))
(set (match_operand:SWI248 0 "general_reg_operand")
(match_operand:SWI248 1 "general_reg_operand"))
(parallel [(set (reg FLAGS_REG) (match_operand 5))
(set (match_dup 0) (match_operand:SWI248 6))])
(set (match_dup 0)
(if_then_else:SWI248 (match_operator 4 "ix86_comparison_operator"
[(reg FLAGS_REG) (const_int 0)])
(match_dup 0)
(match_dup 2)))]
"TARGET_CMOVE
&& REGNO (operands[2]) != REGNO (operands[0])
&& REGNO (operands[2]) != REGNO (operands[1])
&& peep2_reg_dead_p (2, operands[1])
&& peep2_reg_dead_p (4, operands[2])
&& !reg_overlap_mentioned_p (operands[0], operands[3])"
[(parallel [(set (match_dup 7) (match_dup 8))
(set (match_dup 1) (match_dup 9))])
(set (match_dup 0) (match_dup 3))
(set (match_dup 0) (if_then_else:SWI248 (match_dup 4)
(match_dup 1)
(match_dup 0)))]
{
operands[7] = SET_DEST (XVECEXP (PATTERN (peep2_next_insn (2)), 0, 0));
operands[8] = replace_rtx (operands[5], operands[0], operands[1], true);
operands[9] = replace_rtx (operands[6], operands[0], operands[1], true);
})
The conditions make sure that the 2<-3 and 0<-1 moves are independent,
but they don't check what effect the 2<-3 move has on the third
instruction. I don't know if the intention was to exclude cases
where operands 5 and 6 reference operand 2, or whether the intention
was to cope with those cases where possible.

The "dec" above in fact matches many other instructions, including:
(insn 485 960 737 19 (parallel [
(set (reg:CCC 17 flags)
(compare:CCC (plus:DI (reg:DI 43 r15 [orig:157 _138 ] [157])
(reg:DI 3 bx [orig:99 _23 ] [99]))
(reg:DI 3 bx [orig:99 _23 ] [99])))
(set (reg:DI 43 r15 [orig:157 _138 ] [157])
(plus:DI (reg:DI 43 r15 [orig:157 _138 ] [157])
(reg:DI 3 bx [orig:99 _23 ] [99])))
]) "pr107404.cpp":28:46 413 {*adddi3_cc_overflow_2}
(nil))
So, the processed sequence is:
bx <- [mem]
r15 <- r8
r15 <- r15 + bx
r15 <- (r15, bx)
and the sequence is converted to:
r8 <- r8 + bx
r15 <- [mem]
r15 <- (r8, r15)
However, the bx register in the first insn is uninitialized.
We can still allow unrelated registers in the "dec" instruction, under the
condition this register is not the one in the removed assignment. So, the
answer to:
> The conditions make sure that the 2<-3 and 0<-1 moves are independent,
> but they don't check what effect the 2<-3 move has on the third
> instruction. I don't know if the intention was to exclude cases

is that we want to exclude cases where operand 6 references operand 2 (please
note that operand 5 is a duplicate of operand 6).

i386: Fix uninitialized register after peephole2 conversion [PR107404]
The eliminate reg-reg move by inverting the condition of
a cmove #2 peephole2 converts the following sequence:
473: bx:DI=[r14:DI*0x8+r12:DI]
960: r15:DI=r8:DI
485: {flags:CCC=cmp(r15:DI+bx:DI,bx:DI);r15:DI=r15:DI+bx:DI;}
737: r15:DI={(geu(flags:CCC,0))?r15:DI:bx:DI}
to:
1110: {flags:CCC=cmp(r8:DI+bx:DI,bx:DI);r8:DI=r8:DI+bx:DI;}
1111: r15:DI=[r14:DI*0x8+r12:DI]
1112: r15:DI={(geu(flags:CCC,0))?r8:DI:r15:DI}
Please note that(insn 1110) uses register BX, but its
initialization was eliminated.
Avoid conversion if eliminated move intialized a register, used
in the moved instruction.

i386: Fix uninitialized register after peephole2 conversion [PR107404]
The eliminate reg-reg move by inverting the condition of
a cmove #2 peephole2 converts the following sequence:
473: bx:DI=[r14:DI*0x8+r12:DI]
960: r15:DI=r8:DI
485: {flags:CCC=cmp(r15:DI+bx:DI,bx:DI);r15:DI=r15:DI+bx:DI;}
737: r15:DI={(geu(flags:CCC,0))?r15:DI:bx:DI}
to:
1110: {flags:CCC=cmp(r8:DI+bx:DI,bx:DI);r8:DI=r8:DI+bx:DI;}
1111: r15:DI=[r14:DI*0x8+r12:DI]
1112: r15:DI={(geu(flags:CCC,0))?r8:DI:r15:DI}
Please note that(insn 1110) uses register BX, but its
initialization was eliminated.
Avoid conversion if eliminated move intialized a register, used
in the moved instruction.
