[Bug rtl-optimization/64156] Subversion id 218266 breaks the big-endian 64-bit PowerPC build (wilco.dijks...@arm.com's mod to ira-costs.c)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64156
--- Comment #3 from Wilco wdijkstr at arm dot com ---
(In reply to Michael Meissner from comment #2)
Note, the fix proposed in PR64151 DOES NOT work on the PowerPC, so it may be
a dup in terms of what change broke the build, but the potential fix needs
more analysis.
The basic issue is similar, we end up with negative mem_cost for some constant
loads due to LEGITIMATE_PIC_OPERAND_P being true for (symbol_ref:SI
(*.LANCHOR0) [flags 0x182]) in:
(insn 41 40 42 9 (set (reg/f:SI 173)
(mem/u/c:SI (unspec:SI [
(symbol_ref/u:SI (*.LC1) [flags 0x2])
(reg:SI 30 30)
] UNSPEC_TOCREL) [3 S4 A8])) powisf2.c:15 403
{*movsi_internal1}
(expr_list:REG_EQUIV (symbol_ref:SI (*.LANCHOR0) [flags 0x182])
(nil)))
(insn 42 41 43 9 (set (reg:SF 172)
(mem/u/c:SF (reg/f:SI 173) [1 S4 A32])) powisf2.c:15 409
{movsf_hardfloat}
(expr_list:REG_DEAD (reg/f:SI 173)
(expr_list:REG_EQUIV (const_double:SF 1.0e+0 [0x0.8p+1])
(nil
The interesting thing here is that the 2nd load is already processed in the
same way (as it is a legitimate constant. The original costs are 264 for r172
and 0 for r273. However if the first load has its mem_cost changed too, then
BOTH r172 and r173 end up with a negative cost (-198 and -66). Also both loads
are single-use and already right next to their use, so in principle don't need
this mem_cost adjustment as they cannot be spilled.
When the first load is rematerialized in reload it seems to be copied
incorrectly (possibly because the REG_EQUIV is lost at some point), resulting
in an odd LC2 symbol:
(insn 80 42 81 9 (set (reg:SI 9 9)
(mem/u/c:SI (unspec:SI [
(symbol_ref/u:SI (*.LC2) [flags 0x2])
(reg:SI 30 30)
] UNSPEC_TOCREL) [3 S4 A8])) powisf2.c:15 403
{*movsi_internal1}
(nil))
It seems this issue could happen without the mem_move cost adjustment, say for
example if the first load had been CSEd and used for several constants across a
large function. In that case it might be spilled due to register pressure, so
if reload cannot rematerialize it correctly, it should keep the original load
instruction and force a standard spill/reload instead.
Anyway it looks like this patch has triggered some complex allocation issues,
so it seems best to revert it. I'll get someone to do that tomorrow unless
someone else has already done it by then.

[Bug target/64160] New: msp430 code generation error adding 32-bit integers
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64160
Bug ID: 64160
Summary: msp430 code generation error adding 32-bit integers
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: pab at pabigot dot com
This program:
struct adjustment {
unsigned long duration;
};
unsigned long read_clock ();
int dosomething (struct adjustment * ap, unsigned long v);
int doit (struct adjustment * ap)
{
return dosomething(ap, read_clock() + ap-duration);
}
when compiled with msp430-elf-gcc -Os -S produces:
; start of prologue
PUSHM.W #1, R10
; end of prologue
MOV.W R12, R10
CALL#read_clock
MOV.W @R10, R13-- error half of return value clobbered
ADD R12, R13 ; cy
MOV.W 2(R10), R14
ADDCR13, R14 -- R13 is not what it should be
MOV.W R10, R12
CALL#dosomething
which produces the wrong answer because the upper word of the result from
read_clock was overwritten by the read from memory.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64010 --- Comment #7 from Peter A. Bigot pab at pabigot dot com --- I don't know if https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64160 is related; it appears to be a similar problem affecting a value returned in multiple registers. It's present both before and after the alternative patch was applied (now that the code that reset the target has been fixed).

[Bug rtl-optimization/64156] Subversion id 218266 breaks the big-endian 64-bit PowerPC build (wilco.dijks...@arm.com's mod to ira-costs.c)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64156 --- Comment #4 from Vladimir Makarov vmakarov at gcc dot gnu.org --- (In reply to Wilco from comment #3) Anyway it looks like this patch has triggered some complex allocation issues, so it seems best to revert it. I'll get someone to do that tomorrow unless someone else has already done it by then. Yes, it is better to revert the patch, Wilco. The fixing a problem in reload (and ppc uses reload by default) is very tricky. It can take long time (might be weeks) to fix it even if you have a big expertise in reload pass. So there is no real solution besides reverting the patch.
[Bug c++/64110] [5 Regression] ICE: Max. number of generated reload insns per insn is achieved (90)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64110 --- Comment #7 from Vladimir Makarov vmakarov at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #6) Vlad, can you please have a look? Thanks. I'll work on this. But the related code in LRA is very tricky. It can take a few days to fix it and a lot of testing too.
[Bug middle-end/64017] Support ISL 0.14.0 (to fix ICE with gfortran.dg/graphite/pr42393.f90)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64017 --- Comment #5 from howarth at bromo dot med.uc.edu --- Do we still need to be passing -DCLOOG_INT_GMP from config/isl.m4 now that the cloog support is fully deprecated in gcc 5.0?
[Bug go/64001] gccgo: crash on stack splitting
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64001 --- Comment #3 from Ian Lance Taylor ian at airs dot com --- On GNU/Linux gdb can usually print TLS variables fine. It knows how to look up the value for the current thread. Make sure you are using a sufficiently new version of gdb, although I think it's been supported for a few years now.
[Bug fortran/28154] SPREAD (and friends) on unallocated arrays
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=28154 Sean Santos quantheory at gmail dot com changed: What|Removed |Added CC||quantheory at gmail dot com --- Comment #1 from Sean Santos quantheory at gmail dot com --- I don't think that the original bug report here is quite right. See here: real,allocatable :: bar(:,:),foo(:) allocate(foo(0)) bar = spread(foo,dim=1,ncopies=1) print *, shape(bar) end This prints: 1 0 That's perfectly correct; bar is allocated according to Fortran semantics, but of size 0. However, there's this related case where foo is never allocated, which seems to be what the OP was talking about: real,allocatable :: bar(:,:),foo(:) bar = spread(foo,dim=1,ncopies=1) print *, shape(bar) end This is not a legal use of a non-allocated variable, but -fcheck=all misses it. If you run, you get: 1 1 Which is nonsense.
