[Bug debug/41353] VTA missed-debug issues

[aoliva at gcc dot gnu dot org]

--- Comment #15 from aoliva at gcc dot gnu dot org  2009-10-06 06:09 ---
Err, I messed up my testing.  #c9 is not fixed, I was looking at cprop dumps
(as in #c10), not regmove.  Sorry.  Looking into it now.

[Bug debug/41353] VTA missed-debug issues

[aoliva at gcc dot gnu dot org]

--- Comment #14 from aoliva at gcc dot gnu dot org  2009-10-06 06:05 ---
The patch that introduces debug temps fixes the problem in #c9.
http://gcc.gnu.org/ml/gcc-patches/2009-10/msg00112.html

As for the testcase in #c10, the behavior is correct.  If the pseudo holding a
value becomes dead at a certain point, we shouldn't reference the dead value in
subsequent debug insns because, well, it is dead.  Trying to keep it alive
would do us no good: it would likely cause codegen differences.

Now...  Maybe we could make room for finding the value in alternate locations,
adding a debug temp insn right before the death of the pseudo, and referencing
the debug temp instead of the pseudo itself.  This wouldn't help if it's the
only location known to hold the value, and that location gets actually
clobbered afterwards, say if a register gets reused.  We might end up with lots
of useless debug stmts.  However, if the value survives, or is found at an
equivalent location, we might still represent it, but should we?  If we found
the value to be dead, wouldn't it be more accurate to say so?

Neither -O3 or __attribute__((always_inline)) work.  There are four
instances of "\\(DIE \\(.*?\\) DW_TAG_lexical_block" and "\\(DIE \\(.*?\\)
DW_TAG_lexical_block" in the assembly output.  Reviewing the assembler,
all functions are inlined.

The test doesn't fail on trunk.

The test fails in the same way on hppa64-hp-hpux11.11.

I pointed out in my review that this was inappropriate, both because of 
the hardcoding of .comm syntax and because the name is in the user 
namespace.  The LTO people need to reread my comments (on all the patches, 
not just this one) and look for any others that have not been addressed or 
had PRs filed.

http://gcc.gnu.org/ml/gcc-patches/2009-09/msg02139.html has these 
particular comments.

I'll take a look at perhaps just setting...

 in darwin.c's overrides when targeting <10.6 and adjusting
darwin_emit_unwind() to not emit labels when targeting >=10.6.

[Bug c++/41596] handling of library-related options by g++spec.c causes a failure when generating pch.

Created an attachment (id=18715)

allow specification of -static-libstdc++ on the CL while generating PCH

this patch alters the behavior of g++spec.c such that it 
(a) notes if libstdc++ is needed
(b) notes if the user has requested static-libstdc++

It only outputs "-lstdc++" if the lib is needed- and when it does it decides on
the mechanism depending on the availability of static options. 

Finally, for platforms that don't have Bstatic/Bdynamic - it places
"static-libstdc++" back into the command line so that link specs can use it to
trigger substitution.

log:
  *gcc/cp/g++spec.c(lang_specific_driver): Do not insert -lstdc++ unless we
really need it.  
   Insert 'static-libstdc++' for platforms without Bstatic/Bdynamic to
allow link spec substitution.

[Bug c++/41596] New: handling of library-related options by g++spec.c causes a failure when generating pch.

[developer at sandoe-acoustics dot co dot uk]

The recognition of any library-related option in g++-spec.c causes the
insertion of  "-lstdc++".  This causes link to be invoked when trying to
generate PCH, which then fails.  This bit me when trying to run the testsuite
with /-static-libstdc++

The behavior here appears to differ from gcc where one can put "-static-libgcc"
on the CL and the link phase is not invoked for PCH-generation.

Jakub,
   Do you mean that we need to pass 'second' from gcc/ira-int.h?

  /* Allocnos connected by the copy.  The first allocno should have
 smaller order number than the second one.  */
  ira_allocno_t first, second;

to darwin_emit_unwind_label()? Also, what would we use to detect whether the
first and second FDE's came from hot or cold sections?

Doubt it is the same as 40992 as this does not use inline-asm that much.

The problem usually stems from using the wrong tar to untar it.
GNU tar is usually the best tar to use for the gcc sources.

[Bug ada/41416] Conversion Float to fixed-point behaves differently for static expressions

[dirk dot herrmann-privat at gmx dot de]

--- Comment #2 from dirk dot herrmann-privat at gmx dot de  2009-10-05 
16:48 ---
Hi,

thanks for considering my report.

The relevant sections seem to be (these were pointed out to me on comp.lang.ada
by Adam Beneschan):

4.9(38) : "For a real static expression that is not part of a larger static
expression ... the implementation shall round or truncate the value (according
to the Machine_Rounds attribute of the expected type) to the nearest machine
number of the expected type...".

4.9(38.1/2): "The rounding of static floating point expressions is
implementation-defined. It is recommended that the rounding be the same as the
default rounding on the target system."

A.5.4(3): S'Machine_Rounds: Yields the value True if rounding is performed on
inexact results of every predefined operation that yields a result of the type
T; yields the value False otherwise. The value of this attribute is of the
predefined type Boolean.

Here's the interpretation (for which I also used some input from comp.lang.ada
by Adam Beneschan):

4.9(38) demands rounding or truncation for real static expressions, depending
on the value of Machine_Rounds.  A.5.4(3) is not limited to static expressions,
but relates "Machine_Rounds = True" to rounding.  The behaviour in case of
"Machine_Rounds = False" is left open by A.5.4(3), though.  The implementation
advice in 4.9(38.1/2) recommends that static rounding should be the same as the
default rounding.

There is no explicit statement with respect to how non-static expressions
should be handled in case of "Machine_Rounds = False".  But, 4.9(38.1/2) can be
interpreted such that it is generally desired that static and non-static
behaviour should match.  Therefore: 4.9(38) demands truncation for static
expressions in case of "Machine_Rounds = False", and it seems plausible to me
that this should then also apply for non-static expressions.

Thanks again,
Dirk

I think it's a libelf bug.  I'll report it upstream.  In addition, I'll
check if STDC_0_IN_SYSTEM_HEADERS is still necessary on Solaris 2.

With the attached simple lto test case I would have expected f1 and f2 and y to
be optimized away when built with -fwhole-program. But that was not the case.
