[Bug target/81863] [7 regression] -mword-relocations is unreliable
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81863 --- Comment #5 from Yvan Roux --- Thinking more about it, I think that the right place to fix it is in the define of TARGET_HAVE_MOVT or TARGET_USE_MOVT, but I'm a bit confused with these two macros. My understanding of their semantic, is that it should be in TARGET_USE_MOVT (the chip has movt support but we don't want to use it with when -mword_relocations is used), but if we do so the issue movw/movt will be generated anyway since arm_movt pattern and "j" contraint uses TARGET_HAVE_MOVT. In fact, it seems to me that most of TARGET_HAVE_MOVT should be replaced by TARGET_USE_MOVT. Kyrill, Thomas can you educate me ?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81863 Yvan Roux changed: What|Removed |Added CC||yroux at gcc dot gnu.org --- Comment #4 from Yvan Roux --- My quick understanding is that to prevent LRA generating invalid high/lo_sum code, arm_valid_symbolic_address_p (introduced at r227129) needs to be strengthen and check that target_word_relocations is not defined when an addend is present. I'll prepare a patch for that shortly.

--- Comment #6 from Yvan Roux ---
Hi,
I got a small issue when testing the backport into the branch:
g++.dg/lto/pr80287_0.C is not a suitable testcase for GCC 6 branch, since it
uses c++17 class std:any which is not available in GCC 6. In the first place
this bug was found when building
libstdc++-v3/testsuite/20_util/any/assign/2.cc, but it is not related to
std:any, I found it on my side in ceph package build, and the issue is
exhibited when compiling this reduced testcase with -g:
struct A {
operator long() {}
} __attribute__((__may_alias__));
struct {
A ino;
} a;
char b = a.ino;
So, I wonder what is the best way to handle that, adding this new testcase on
trunk as g++.dg/pr80287.C and only backport this one into GCC 6, or avoid
std:any usage into g++.dg/lto/pr80287_0.C ?

For me when the vectors have two elements ZIP, UZIP and TRN instruction give the same result. for instance if we have: + -+--+ Vn | A1 | A0 | + -+--+ Vm | B1 | B0 | + -+--+ UZIP1 reads the even-numbered elemenents of Vn (i.e A0), places it in the lower half of Vd and then do the same with Vm, thus we have: + -+--+ Vd | B0 | A0 | + -+--+ ZIP1 reads the first pair from Vn (which is only A0 is this case) and places it into the lowest element of Vd and then do same with Vm to get them interleaved, thus we also have: + -+--+ Vd | B0 | A0 | + -+--+ Maybe the confusion comes from the revision of the manual you looked at, which doesn't include detailled explanation of these instructions, DDI0487A_k includes figures. Kyrill, in the UZP1 figures (C7.2.346) it show that the first unzipped vector is from Vn ... but maybe I'm the one who misundertand the description ! ;)

The issue is that the movdi pattern calls gen_lowpart (SImode, operands[0]), operands being in DImode, but the mode of the register cannot be changed as it is explained in the macro CANNOT_CHANGE_MODE_CLASS definition: "In big-endian mode, modes greater than word size (i.e. DFmode) are stored in VFP registers in little-endian order. We can't describe that accurately to GCC, so avoid taking subregs of such values." Thus, gen_lowpart_general makes a copy of that register and copy it, which calls again emit_move_insn and gen_movdi and so on ... I've a patch under test that prevent doing this when the mode of a register can't be changed, but the regression discussed in this thread may be back then... https://gcc.gnu.org/ml/gcc-patches/2015-07/msg00216.html

The PR fix changes some IRA cost which makes it choose a IWMMXT_REGS (instead of a GENERAL_REGS one) for the result of iwmmxt_arm_movdi insn and the alternatives of this pattern make LRA stuck in a loop. The -fuse-caller-save patch fixed the issue because it adds IP and CC cloobers to CALL_INSN_FUNCTION_USAGE, which changes the register allocation (a GENERAL_REGS is selected this time), but the real issue is in the alternatives description of iwmmxt_arm_movdi insn. I've a patch for it that I'll submit.
