[Bug target/71680] [7 Regression] ICE: Max. number of generated reload insns per insn is achieved (90) w/ -Os -mlra
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71680 --- Comment #9 from Alan Modra --- lra doesn't load in SFmode due to the following condition in lra-constraints.c:simplify_operand_subreg /* If we change address for paradoxical subreg of memory, the address might violate the necessary alignment or the access might be slow. So take this into consideration. We should not worry about access beyond allocated memory for paradoxical memory subregs as we don't substitute such equiv memory (see processing equivalences in function lra_constraints) and because for spilled pseudos we allocate stack memory enough for the biggest corresponding paradoxical subreg. */ if (MEM_P (reg) && (! SLOW_UNALIGNED_ACCESS (mode, MEM_ALIGN (reg)) || MEM_ALIGN (reg) >= GET_MODE_ALIGNMENT (mode))) MEM_ALIGN here is 8 bits (from #pragma pack, and yes, the mem really is only byte aligned), and rs6000.h does say that this access might be slow if in SFmode. It's true that an unaligned floating point storage access on power might cause an alignment trap, so leaving aside the issue that mode only maps loosely to register class, I think the rs6000.h definition of SLOW_UNALIGNED_ACCESS is correct and lra is doing the right thing here. Reload is wrong to use a fp load (if mem align was always accurate, which it isn't). Hmm, a change that doesn't cure this problem, but the condition might be better as if (MEM_P (reg) && (! SLOW_UNALIGNED_ACCESS (mode, MEM_ALIGN (reg)) || SLOW_UNALIGNED_ACCESS (innermode, MEM_ALIGN (reg)) || MEM_ALIGN (reg) >= GET_MODE_ALIGNMENT (mode))) ie. if both innermode and mode are slow then lra may as well go ahead and use the subreg mode.

I checked r237473 plus the patch against r237472 and the regression was fully fixed. I did not yet check current trunk but if there is any regression it is a new one caused by sth else.

[Bug libgcc/68468] frv/bfin toolchain build error
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68468
--- Comment #8 from Waldemar Brodkorb ---
The first bug report was a wrong configuration of uClibc for FR-V.
The version I used allowed me to use FLAT instead of FDPIC.
Now I understand that FR-V is FDPIC only and BFIN is either FDPIC or FLAT.
But my comment from 2016-07-25 contains the problem I am still facing.
So the struct is defined, but later on there incompatible data types used:
error: incompatible types when assigning to type 'struct elf32_fdpic_loadaddr'
from type '_Unwind_Ptr {aka unsigned int}'
load_base = cache_entry->load_base;
What's wrong?
I can upload full fr-v build log, if the bfin build log isn't enough.
But I think a gcc developer might see the problem directly in the code.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71949 --- Comment #3 from joseph at codesourcery dot com --- atomic_flag can't have additional state for locks because it's lock-free, but it may still be the case that it needs to be initialized in a special way to have a valid set or clear value (that is, that a non-trivial struct initializer is needed - note that compound literals are *not* valid for static struct initializers in ISO C, only braced initializers are). The specification that the macro is only valid as an initializer still applies, whether or not it's valid to use atomic_flag_clear on an uninitialized atomic_flag (I think it's obviously not valid to use atomic_flag_test_and_set on such a variable).

Use -Warray-temporaries, using a compiler with and one without the patch. The compiler with the patch should be missing a warning about creating an array temporary. Create a minimum test case containing just the offending line, plus any declarations that are needed to make it valid. Check if the two compilers still exhibit the difference with -Warray-temporaries. Voila, minimum test case! BTW, I will only have time to work on this in around two weeks. With a test case, it would be OK with me if somebody reverted the patch. I can then rework it to take care of that particular bug.

--- Comment #8 from Alan Modra ---
From -m32 -O2 dumps of Anton's testcase:
(insn 8 9 33 3 (set (reg:SI 160 [ a ])
(mem/c:SI (reg/f:SI 162) [1 a+0 S4 A8]))
/home/alan/src/tmp/pr71680.c:13 464 {*movsi_internal1}

(expr_list:REG_EQUAL (mem/c:SI (symbol_ref:SI ("a") [flags 0x84]
) [1 a+0 S4 A8])
(nil
Looking at the insn that loads reg 160 above, you'll notice movsi_internal1,
which doesn't have an alternative to allow an fpr as is required by insn 32.
What's more, SImode isn't allowed in fprs (see rs6000_hard_regno_mode_ok) so it
doesn't make sense to add such an alternative.
What happens in reload is that reg 160 equiv mem is substituted into insn 32
then reload cleverly reloads the subreg:
Reloads for insn # 32
Reload 0: reload_in (SF) = (mem/c:SF (reg/f:SI 31 31 [162]) [1 a+0 S4 A8])
FLOAT_REGS, RELOAD_FOR_INPUT (opnum = 1), can't combine
reload_in_reg: (subreg:SF (reg:SI 160 [ a ]) 0)
reload_reg_rtx: (reg:SF 44 12)
So we load from mem in SFmode, and insn 8 is deleted. lra apparently doesn't
use the trick of changing to the mode of the subreg.

This is happening on SH on the AMS branch in CSiBE/OpenTCP/ip.c:
unsigned short ip_checksum(unsigned short, char, char);
unsigned long ip_checksum_buf (unsigned short cs, char* buf, unsigned short
len)
{
unsigned short dat;
unsigned long temp;
temp = cs;
while(len>1)
{
len -= 2;
dat = *buf++;
dat <<= 8;
dat |= *buf++;
temp += dat;
}
temp = (temp >> 16) + (temp & 0x);
temp += (temp >>16);
if(len)
temp = ip_checksum(temp, *buf, 0);
return( (unsigned short) temp );
}
Without AMS, before combine there are the two insns:
(insn 80 78 81 4 (set (reg:QI 257 [ MEM[base: _67, offset: 1B] ])
(mem:QI (plus:SI (reg:SI 240 [ ivtmp.12 ])
(const_int 1 [0x1])) [0 MEM[base: _67, offset: 1B]+0 S1 A8]))
sh_tmp.cpp:1549 200 {*movqi_load_mem_disp12}
(nil))
(insn 81 80 82 4 (set (reg:HI 256 [ MEM[base: _67, offset: 1B]+-1 ])
(sign_extend:HI (reg:QI 257 [ MEM[base: _67, offset: 1B] ])))
sh_tmp.cpp:1549 177 {*extendqihi2_compact_reg}
(expr_list:REG_DEAD (reg:QI 257 [ MEM[base: _67, offset: 1B] ])
(nil)))
Then during combine:
Trying 80 -> 81:
Failed to match this instruction:
(set (reg:HI 256 [ MEM[base: _67, offset: 1B]+-1 ])
(sign_extend:HI (mem:QI (plus:SI (reg:SI 240 [ ivtmp.12 ])
(const_int 1 [0x1])) [0 MEM[base: _67, offset: 1B]+0 S1 A8])))
Trying 80, 81 -> 83:
Failed to match this instruction:
(set (reg:SI 259)
(ior:SI (subreg:SI (mem:QI (plus:SI (reg:SI 240 [ ivtmp.12 ])
(const_int 1 [0x1])) [0 MEM[base: _67, offset: 1B]+0 S1
A8]) 0)
(subreg:SI (reg:HI 258 [ dat ]) 0)))
Successfully matched this instruction:
(set (reg:SI 256 [ MEM[base: _67, offset: 1B]+-3 ])
(sign_extend:SI (mem:QI (plus:SI (reg:SI 240 [ ivtmp.12 ])
(const_int 1 [0x1])) [0 MEM[base: _67, offset: 1B]+0 S1 A8])))
So combine promotes reg 256 from SImode to HImode and everything's good.
The same two initial insns with AMS before combine:
(insn 80 146 81 4 (set (reg:QI 257 [ MEM[base: _67, offset: 1B] ])
(mem:QI (post_inc:SI (reg:SI 480)) [0 MEM[base: _67, offset: 1B]+0 S1
A8])) sh_tmp.cpp:1549 202 {*movqi}
(expr_list:REG_INC (reg:SI 480)
(nil)))
(insn 81 80 82 4 (set (reg:HI 256 [ MEM[base: _67, offset: 1B]+-1 ])
(sign_extend:HI (reg:QI 257 [ MEM[base: _67, offset: 1B] ])))
sh_tmp.cpp:1549 177 {*extendqihi2_compact_reg}
(expr_list:REG_DEAD (reg:QI 257 [ MEM[base: _67, offset: 1B] ])
(nil)))
Then combine does:
Trying 80 -> 81:
Failed to match this instruction:
(set (reg:HI 256 [ MEM[base: _67, offset: 1B]+-1 ])
(sign_extend:HI (mem:QI (post_inc:SI (reg:SI 480)) [0 MEM[base: _67,
offset: 1B]+0 S1 A8])))
...
Trying 80, 81 -> 83:
Failed to match this instruction:
(set (reg:SI 259)
(ior:SI (subreg:SI (sign_extend:HI (mem:QI (post_inc:SI (reg:SI 480)) [0
MEM[base: _67, offset: 1B]+0 S1 A8])) 0)
(subreg:SI (reg:HI 258 [ dat ]) 0)))
Failed to match this instruction:
(set (reg:HI 256 [ MEM[base: _67, offset: 1B]+-1 ])
(sign_extend:HI (mem:QI (post_inc:SI (reg:SI 480)) [0 MEM[base: _67,
offset: 1B]+0 S1 A8])))
As a consequence, the redundant sign extension after the actually
sign-extending mem-load remains. At the moment it seems that only adding more
patterns to the MD helps:
(define_insn "*extendhi2_compact_snd"
[(set (match_operand:HI 0 "arith_reg_dest" "=r")
(sign_extend:HI
(match_operand:QIHI 1 "movsrc_no_disp_mem_operand" "Snd")))]
"TARGET_SH1 && false"
"mov. %1,%0"
[(set_attr "type" "load")])
[Bug fortran/72709] New: Incorrect assignment of allocatable character array used as component of derived type
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72709
Bug ID: 72709
Summary: Incorrect assignment of allocatable character array
used as component of derived type
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

In the following program the assignment to character array element doesn't work
programread_exp_data
implicit none
type experimental_data_t
integer :: nh = 0
character(len=:), dimension(:), allocatable :: header
end type experimental_data_t
type(experimental_data_t) :: ex
integer :: nh_len
integer :: i
nh_len = 255
ex % nh = 3
allocate(character(len=nh_len) :: ex % header(ex % nh))
ex % header(1) = "#Generated by X"
ex % header(2) = "#from file 'Y'"
ex % header(3) = "# Experimental 4 mg/g"
do i = 1, ex % nh
write(*,*) "header(",i,") = ", ex % header(i)
enddo
end program read_exp_data
I get all 3 header elements = "# Experimental 4 mg/g"

[Bug tree-optimization/72517] [7 Regression] 436.cactusADM: More than 40% regression in O3 and Ofast on AMD bdver4 m/c.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72517 --- Comment #8 from Richard Biener --- As for the cost model the vectorizer uses vec_to_scalar for element extraction which it was not originally added for (it was added for the cost of extracting element zero only). Ok, so I can reproduce the regression (-Ofast -march=native): 436.cactusADM 11950304 39.3 * 11950420 28.5 * The function that regresses is bench_staggeredleapfrog2_ (that was probably obvious). The set of vectorized loops / BBs does _not_ change with the patch. We do a lot less work in dependence analysis after the patch as no read-read dependences are computed which unfortunately had the side-effect of mostly disabling STMT_VINFO_SAME_ALIGN_REFS computation which causes us to peel for alignment for a different DR. I'll revert that part of the change.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58073 --- Comment #5 from dhowells at redhat dot com --- There's a further potential optimisation. If shift is large enough that the bits under test are outside of the LSB, the TESTB changes to a TESTL at the same address: Shift 2: 0: f6 07 1ctestb $0x1c,(%rdi) 3: 0f 94 c0sete %al 6: c3 retq Shift 10: 0: f7 07 00 1c 00 00 testl $0x1c00,(%rdi) 6: 0f 94 c0sete %al 9: c3 retq Shift 18: 0: f7 07 00 00 1c 00 testl $0x1c,(%rdi) 6: 0f 94 c0sete %al 9: c3 retq However, one could do a TESTW or a TESTB instead with a smaller immediate value and a displaced address.

Reducing it would probably prove hard as the bug is a miscompile and therefore only shows at runtime in a >30 second test. H.J. has narrowed the miscompilation down to one file, would it be helpful for you if I generated some diffs of when the dumps first change, and the generated assembly for x86_64?

Richard Biener changed:
What|Removed |Added

--- Comment #3 from Richard Biener ---
Ugh, what a gross usage of a langhook ;) Its default implementation clearly
doesn't match the use in size_in_bytes:
tree
size_in_bytes_loc (location_t loc, const_tree type)
{
tree t;
if (type == error_mark_node)
return integer_zero_node;
type = TYPE_MAIN_VARIANT (type);
t = TYPE_SIZE_UNIT (type);
if (t == 0)
{
lang_hooks.types.incomplete_type_error (loc, NULL_TREE, type);
but the langhook (not sure what the point is in asserting in the no-op
default implementation):
/* Invalid use of an incomplete type. */
void
lhd_incomplete_type_error (location_t ARG_UNUSED (loc),
const_tree ARG_UNUSED (value), const_tree type)
{
gcc_assert (TREE_CODE (type) == ERROR_MARK);
return;
OTOH the early out in size_in_bytes means the langhook can never be safely
used or its assert is bogus. Or the fortran FE messes things up in
unexpected ways (failing to call layout_type on a non-ERROR_MARK type).
