--- Comment #6 from dje at gcc dot gnu dot org 2010-07-21 23:52 --- I think the thread about the patch became confused. First, Janis essentially approved the testsuite patch. Second, Martin commented that the failure probably was due to MOVE_RATIO not defined. The statement caused some misunderstanding. MOVE_RATIO does not need to be defined and the failure is not caused by a missing definition. The default value of MOVE_RATIO (used by PPC and ARM) cause the heuristic to disable the optimization being tested. If the optimization is not expected to occur on some platforms, then the testcase should be disabled as implemented by the patch or the testcase explicitly should set some gcc param that ensures the optimization will occur on all targets. -- dje at gcc dot gnu dot org changed: What|Removed |Added CC||dje at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2010-07-21 23:52:38 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42855
[Bug target/43892] PowerPC suboptimal add with carry optimization
--- Comment #16 from dje at gcc dot gnu dot org 2010-05-27 01:37 --- You have no patience, now do you? Sure I do. It is just that its been almost a month and from the description it sounded like an easy fix: config/rs6000/rs6000.md would need to add a addmodecc expander No you do not have any patience; in fact, your comments are rather obnoxious, such as: its been almost a month. If you do not know what you are talking about, stop talking. No, it is not an easy fix. The high-level concept and description is simple, the implementation is extremely complex and tedious. even though it sounded that the initial fix was easy(addmodecc expander) The fix will be a few thousand lines of patch. Literally. Oops, just to add a cc expander? Yes. Again, if you do not know the complexity of what you are requesting, get more information instead of acting annoyed that people are not jumping to solve your problem. It is not just adding a cc expander. Do you even know what that means or what it involves? For the expander to be effective, the PowerPC port of GCC needs to be taught to track the carry bit, which it currently does not. *ALL* patterns that produce instructions affecting the carry bit must be updated. One cannot add the pattern in isolation. If you do not understand the implications of your request, then *ask* why it is more complicated than you assumed. There is no simple fix. The only fix is the ultimate fix: completely propagating the carry bit throughout the PowerPC port. You apparently have not read the documentation to understand the -mcpu= option or the --with-cpu= configure option. You are making a lot of incorrect assumption and assertions, apparently without making any effort to gain some knowledge before you start writing. That really does not encourage anyone to help you, especially when it requires a lot of work. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43892

--- Comment #8 from dje at gcc dot gnu dot org 2010-05-20 14:25 --- Has anyone tested if generating an instruction sequence that uses the carry bit actually improves performance on modern POWER processors?

[Bug regression/43892] PowerPC suboptimal add with carry optimization
--- Comment #10 from dje at gcc dot gnu dot org 2010-05-21 00:28 --- On my mpc8321 it is a big difference(don't have numbers handy). Why would such a simply insn be a problem performance wise? I know the kernel still uses the carry insn's for calculating the Internet checksum. mpc8321 is a relatively simplistic pipeline. Processors like POWER4, 5, 6, 7 may not have the same characteristics. Even with carry bit register renaming, it is an extra input/output to a dedicated resource, an extra register port. XLC currently avoids carry completely for POWER5 and POWER6: .add32carry: add r5,r3,r4 cmpl0,0,r5,r4 addir3,r5,1 bclrBO_IF,CR0_LT ori r3,r5,0x blr One cannot assume that fewer UISA instructions equates with fewer microarchitecture operations and faster performance. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43892

[Bug tree-optimization/41035] AIX cexp builtin underflow
--- Comment #4 from dje at gcc dot gnu dot org 2009-12-09 16:36 --- I think the problem is bad design of MPFR, not a bug in MPC. GCC uses mpfr_clear_flags(), mpfr_overflow_p() and mpfr_underflow_p() for results of computations in both MPFR and MPC, which uses MPFR. These rely on the MPFR global variable __gmpfr_flags. If libmpfr is a static library and libmpc is a shared library, libmpc and GCC will have their own, private copies of __gmpfr_flags. If both libraries are static or both libraries are shared, only one copy of the variable should exist. There sometimes are reasons to have both shared and static libraries and the current interaction creates a hidden dependency between the libraries. I think it would be a much better design to associate the flag with the variable containing the computational result than some global state. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41035

--- Comment #5 from dje at gcc dot gnu dot org 2009-06-02 12:51 ---
cfgexpand.c:expand_used_vars() expands and instantiates virtual-stack-vars for
INSNs when it walks the partion map:
for (i = 0; i SA.map-num_partitions; i++)
{
tree var = partition_to_var (SA.map, i);
gcc_assert (is_gimple_reg (var));
if (TREE_CODE (SSA_NAME_VAR (var)) == VAR_DECL)
expand_one_var (var, true, true);
It then instantiates the same virtual-stack-vars in debug DECLs when it calls
expand_used_vars_for_block (outer_block, true), which calls
/* Expand all variables at this level. */
for (t = BLOCK_VARS (block); t ; t = TREE_CHAIN (t))
if (TREE_USED (t))
expand_one_var (t, toplevel, true);
The INSN var is an SSA_NAME and expand_one_stack_var_at() uses the alignment in
the DECL; the BLOCK var is not an SSA_NAME and the alignment is computed as the
STACK_BOUNDARY.

--- Comment #2 from dje at gcc dot gnu dot org 2009-04-27 13:54 --- This also fails on AIX. On AIX, the error appears as a failure while compiling libobjc/linking.m. A function in cgraphunit.c is being mis-compiled, possibly build_cdtor(). This causes cgraph_build_static_cdtor() to be called with an invalid priority of -1, instead of 65535. The priority should not be negative. This negative priority value generates an invalid global file function name: _GLOBAL__I_-1_0___objc_linking A function name should not contain a minus sign, which is a syntax error. Recompiling cgarphunit.c without optimization fixes the miscompilation. An incorrect priority is calculated from decl_fini_priority_lookup(), but recompiling tree.c does not change the failure. -- dje at gcc dot gnu dot org changed: What|Removed |Added CC||dje at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 GCC build triplet|powerpc-apple-darwin9 |powerpc-apple- ||darwin9,powerpc-ibm-aix GCC host triplet|powerpc-apple-darwin9 |powerpc-apple- ||darwin9,powerpc-ibm-aix GCC target triplet|powerpc-apple-darwin9 |powerpc-apple- ||darwin9,powerpc-ibm-aix Priority|P3 |P1 Last reconfirmed|-00-00 00:00:00 |2009-04-27 13:54:23 date|| Summary|[4.5 Regression]|[4.5 Regression] |Bootstrapping fails at stage|Bootstrapping fails at stage |1 on powerpc-apple-darwin9 |1 on powerpc-apple-darwin9 ||and powerpc-ibm-aix http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39929

We cannot help you with a compiler that diverges from the FSF tree. Again, I am not sure which versions of GMP and MPFR you are using. I would recommend that you configure and build those packages with --disable-shared and ABI=32. You also can try running cc1plus inside GDB and compiling the files to see where the ICE occurs.

--- Comment #33 from dje at gcc dot gnu dot org 2008-09-16 20:00 --- I have not tried MPFR as a shared library. One thing to be careful about with shared libraries on AIX is libpath. libtool configured for gmp and mpfr decides to hardcode the path and finds all of the GCC build directory paths. I manually edit the configured libtool to cleanup libpath. libgmp.a and libmpfr.a only need /usr/lib:/lib because they do not depend on shared libgcc.a. libgmpxx.a depends on the directories where libstdc++.a and libgcc_s.a are installed. cc1, cc1plus, etc. generally end up with sane libpaths, but libstdc++ (again built by libtool) includes a lot of junk directories. These latter dependencies would not affect the ICEs when building OpenFOAM, but you might want to be aware for the application itself. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37057

--- Comment #17 from dje at gcc dot gnu dot org 2008-09-14 19:52 --- Because the problem is due to garbage collection, it is non-deterministic, depending on what data GCC generates. I was able to reproduce the problem in a recent development version of GCC, prior to Honza's patch, but not in my installed version of GCC 4.3.1, which is why I asked you to confirm that the patch fixes the problem for you. GCC 4.3.2 fixes numerous bugs over GCC 4.3.1, although not necessarily ICEs that affect you. I would recommend using a patched version of GCC 4.3.2 over a patched version of GCC 4.3.1, but that is your decision. -- dje at gcc dot gnu dot org changed: What|Removed |Added Status|NEW |WAITING Target Milestone|--- |4.3.3 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37057

That file failed before Honza's patch and does not appear to fail after his patch. I cannot reproduce the failure using my version of GCC 4.3.1. Saying that the patch does not fix the problem is not accurate. You said that the makeChemkinReactions.ii still was present in GCC 4.3.2, but you report an ICE for chemkinReader.ii. Please stop shifting the goalpost. You have not commented on makeChemkinReactions.ii. No one said that the seven ICEs were do to a single problem. I suspect the makeChemkinReactions.ii ICE *is* fixed. If you attach chemkinReader.ii, we can try to investigate it as well.
