[Bug target/35623] RTL check failure in arm_const_double_rtx

[rmansfield at qnx dot com]

--- Comment #4 from rmansfield at qnx dot com  2009-05-18 03:55 ---
I can no longer reproduce the problem with gcc 4.4.0 or trunk (4.5.0 20090518
revision 147649). I was able to reproduce it with gcc 4.3.3 release.

I'm indifferent to whether the PR is resolved as fixed in 4.4/4.5 or resolved
as wontfix in 4.2.4/4.3.3.

If -o is specified multiple -o options are passed to the assembler,
and the assembly from lto1 is compiled into file specified the user, and the
temporary objfile is empty.

According to the documentation, -mfloat-gprs is only available on the
MPC8540/MPC8548. So should there be a check like the following?

Also, I have another test case which may* cause an ICE in extract_insn, at
recog.c when using -mfloat-gprs=double and -mcpu=common. Since they are caused
by the same invalid combination of switches, should I open a PR for it or will
this one suffice?

*I found the ICE on the e500 branch. The test case is in C++ so I haven't have
time to build powerpc-linux-gnuspe-g++ from the head yet.

[Bug target/29066] ARM eabi C++ ABI mishap

--- Comment #3 from rmansfield at qnx dot com  2006-09-13 20:57 ---
Fails on MIPS as well (and probably other ptrmemfunc_vbit_in_delta targets).
This has been around for awhile since in fails in 3.3 and 3.4. Testcase works
in 2.95.3

I came across the rtl check failure building arm-unknown-nto-qnx (unsupported
target) on the trunk (4.4.0 20080318 (experimental) [trunk revision 133302]) ,
and I was able to reproduce it on the 4.3.x and 4.2.x branches but I didn't see
it on the 4.1.x branch.

I just built a gcc 4.2 arm-unknown-linux-gnu snapshot to confirm the problem
was in the mainline and not a problem with the arm-unknown-nto-qnx target.
Please let me know if you need me to reproduce this with an
arm-unknown-linux-gnu target for 4.3/4.4.

If gcc is configured with --with-sysroot= and

a relative path, and then incpath.c will trip the trailing sysroot

DIR_SEPARATOR and construct an invalid path.

This ICE does happen on trunk (rev190294). I have a testcase for it that I'm
reducing. There was a second ICE introduced by 190259 as well.

I have a local patch re-enabling it, but I don't think it's specific to the

configuration. Do you? I can try to reproduce it on another target..

The patch fixes the crash in emit_cmp_and_jump_insn_1, but not the one in

emit_case_dispatch_table.

I was able to reproduce the crash in emit_case_dispatch_table on a stock 

sh4-unknown-linux-gnu configuration with another testcase. This patch fixes the

all crashes I've seen so far.

emit_case_dispatch_table testcase



Here's a csmith generated testcase that crashes with -O0 -fexceptions on

sh4-unknown-linux-gnu. It's slightly reduced but I can reduce it further by

hand if necessary.

Sorry for being unclear. Yes, it fixes the crash. I was attaching it in as a

Yep, I realize that. I just came across this crash by accidentally leaving
-fvar-tracking-assignments off the link line. Improper usage that cause
crashes/ICEs are still worth PRs, right? 

The non-reduced testcase was built with -O2 as well as a number of other
options for compiling/linking but since they didn't effect whether or not the
crash occurred I left them out of the report.

--- Comment #5 from rmansfield at qnx dot com  2009-09-16 13:55 ---
I will have to reduce the source testcase before I can provide it. I tried to
reproduce this PR with gcc version 4.5.0 20090910 (experimental) [lto revision
151644] (lto merged with rev 150842) and I now hit the ICE reported in PR41173.

lto1: fatal error: internal error: builtin function to __builtin_bswap16
already processed.
compilation terminated.

Also, I had recently seen a couple of verify_stmts ICES on SH4 (using same rev
as the ppc toolchain)

Example #1.

In function 'inflateCopy':
lto1: error: non-trivial conversion at assignment
struct internal_state *
struct inflate_state *
# .MEM_82 = VDEF <.MEM_81>
dest_3(D)->state = copy_16;

lto1: internal compiler error: verify_stmts failed

Example #2.

lto1: error: type mismatch in indirect reference
const struct PtTerminalWidget_t

const struct PtTerminalWidget_t

# VUSE <.MEM_7(D)>
D.140180_2 = term_1(D)->cm.size;

Example #3:

lto1: error: non-trivial conversion at assignment
struct xmlDict *
struct _xmlDict *
# VUSE <.MEM_16(D)>
dict_6 = D.24482_5->dict;


Is one testcase for the sh ICEs enough or one for each ICE?

I can reproduce the x86 ICE with gcc version 4.5.0 20090902 (experimental) [lto
revision 151401] (lto merged with rev 150842).  I will try again with the
latest and reduce a source testcase.

I hit the PR41173 using an updated powerpc-unknown-linux-gnu configuration. 

The x86 ICE is still reproducible using a reduced testcase and a mismatch of
optimizations levels.

Without the langhooks.c patch -flto is currently unusable/untestable

I wasn't able to reproduce the issue with i686-pc-linux-gnu either but the ICE 
happens with arm-unknown-linux-gnu/arm-unknown-nto-qnx6.4.0 as well.
mips-unknown-nto-qnx6.4.0 and sh4-unknown-nto-qnx6.4.0 configurations seemed to
be OK.

[Bug middle-end/50708] New: Infinite loop between rshift_double and lshift_double if count is LONG_MIN

[rmansfield at qnx dot com]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50708

 Bug #: 50708
   Summary: Infinite loop between rshift_double and lshift_double
if count is LONG_MIN
Classification: Unclassified
   Product: gcc
   Version: 4.7.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: middle-end
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rmansfi...@qnx.com
CC: rguent...@suse.de
  Host: i686-unknown-linux-gnu
Target: arm-unknown-linux-gnu
 Build: i686-unknown-linux-gnu


rshift_double() has 

  if (count < 0)
{
  lshift_double (l1, h1, -count, prec, lv, hv, arith);
  return;
}

and lshift_double() has:

  if (count < 0)
{
  rshift_double (l1, h1, -count, prec, lv, hv, arith);
  return;
}

so when count = LONG_MIN, count and -count are the same and end up calling each
forever, or until the process runs out of stack.

The backtrace shows the issue:

My large testcase reduced to:

void
foo ()
{
  unsigned int a = 1 << 0x8000;
}

arm eabi targets force 64bit HOST_WIDE_INT which is why the reduced testcase
didn't fail.

This is a target bug but it's related to bug 7618 (which was mips specific).
