No just the duplicated memcpy. not inlining memcpy is most likely not a bug, just tunning differences. If you want it inlined you should use -minline-all-stringops which just inlines always most of standard C string functions including memcpy but you should do timings before you do that because memcpy can be optimized for your target more than what gets inlined. For an example it could use SSE registers to do the copy if they exist. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29375

Also, are you saying that the fix for PR23372 also brings us back to avoiding direct calls to memcpy?

[Bug target/25477] builtin functions should use $LDBL128 suffix on darwin when appropriate
--- Comment #8 from geoffk at gcc dot gnu dot org 2006-10-06 19:20 --- The general problem here is that on PPC Darwin, when using gcc with -mlong-double-128 (which is the default), some system functions (you can find a list in bug 25850) need to have $LDBL128 appended to their assembly names. For the variadic functions, like printf, which might not have any long doubles passed to them, this should happen only when compiling for 10.3.9 and later, since these functions aren't available earlier; the user needs to avoid calling those functions with long doubles when compiling with a -mmacosx-version-min of less than 10.3.9. -- geoffk at gcc dot gnu dot org changed: What|Removed |Added GCC target triplet|*-*-darwin[789]*|powerpc-*-darwin[789]* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25477
[Bug libstdc++/29095] [4.0/4.1/4.2 Regression] cxxabi.h __cxa_cdtor_type not declared when included from "C"
--- Comment #7 from mmitchel at gcc dot gnu dot org 2006-10-06 19:18 --- I'm following up to the mailing list in the PR trail, since it's very confusing to go back and forth between the two. The technical issue is that in the following code: extern "C" { typedef void (*p1)(); } typedef void (*p2)(); p1 and p2 are distinct types, and, in fact, you can overload based on that. G++ doesn't implement that distinction; we don't keep track of language linkage for types (just for functions) but we should, and, at some point, I'm sure we'll implement that. The reason this is in the standard is so that an implementation can use different calling conventions for C and C++. So, when calling through a function pointer you have to know which kind of function you're calling. (And, yes, name-mangling is supposed to encode the linkage of the function type, when mangling a pointer-to-function type.) So, changing the linkage of __cxa_cdtor_return_type (that name is not specified in the ABI, by the way), technically changes the type of __cxa_vec_new. However, the ABI specification does say that __cxa_vec_new is declared extern "C", and, since it specifically gives this prototype: extern "C" void * __cxa_vec_new ( size_t element_count, size_t element_size, size_t padding_size, void (*constructor) ( void *this ), void (*destructor) ( void *this ) ); that means that the type of the constructor and destructor arguments are also required to be pointers-to-C-functions. In summary, I think Benjamin's proposed change (to change the constructor type to have extern "C" linkage) is in fact required by the ABI. Although it's technically a source-incompatible change, since G++ doesn't implement linkage for function pointers, there's no way that a user of G++ can tell the difference. Therefore, I think that's the right thing to do. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29095

I would be interested in seeing the functions because gfortran currently can't constant fold a TRANSFER() of the form real, parameter :: x = transfer(1234,x) This is a bitwise copy of the integer 1234 into x. In gfortran 1235 is a gmp mpz_t type and x is an mpfr mpfr_t type.

I think using long double defeats the whole purpose of using mpfr. We're supposed to avoid relying on the properties of the host's floating point for cross-compilers where the target format is different. Otherwise I could simply call out to e.g. cosl() on the host and avoid the whole mpfr thing (okay okay, assuming cosl() and the rest of c99 math functions exist... which they don't always, but my point about target long double remains.)

--- Comment #5 from eplondke at gmail dot com 2006-10-06 14:55 --- Here's what's going on in this case: CSE changes an address if: A) The cost of the address is lower or B) The cost of the address is the same and the cost of the RTX would be higher outside of an address So, CSE changes (R) to (R+4) because it is lower cost as specified by the address_costs hook. It doesn't change beyond (R+4) because (R+8) is the same cost as (R+4). Once the address (R+4) gets in the RTL sequence, it never gets converted to a postincrement form. So by adding the cost of a simple REG RTX as being lower than (+ (REG) (CONST)) in the addressing modes, CSE doesn't convert the address to base+offset, and we get the postincrement code back again in 4.x. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29294

[Bug middle-end/29335] transcendental functions with constant arguments should be resolved at compile-time

I looked through those and read through the mpfr docs so I think I have a good idea of what mpfr can do. My main area of concern right now is converting between gcc's REAL_VALUE_TYPE and mpfr_t. I found gfc_conv_mpfr_to_tree() in trans-const.c which uses a string as an intermediate type, is that the most efficient way to convert? Also where is the function that does the reverse, i.e. tree or REAL_VALUE_TYPE to mpfr_t? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29335

In particular, it should not be the same address as the parent function. I seem to recall that in previous versions (2.95.x, 3.x) of GCC __cyg_profile_func_enter() used the call location of an inlined function as first argument. This is somewhere in the middle of the parent function, which makes sense somehow. Any invalid address could be used as well.

for 4.2 versions of the policy-based associated containers, the individual debug macros were stripped out and the usual libstc++-designating-debug-mode macro was used. This is: _GLIBCXX_DEBUG. While doing this, I found a long-standing issue with the pb_ds hash-based containers and the debug mode: parts are missing. This isn't the case for tree and priority_que data structures, which work perfectly. This is apparently an issue for every version of pb_ds and pb_assoc that I've seen.

[Bug libstdc++/29366] New: atomics config for sh is wierd
The atomics configury for sh in libstdc++ is quite poor, and duplicates the generic atomicity files if __SH4A__ is undefined. This is the only cpu directory to do this, and leads to issues when the genric atomicity code is updated: twice now the sh config has been left behind. This is no good. Let's try to fix it. See: config/cpu/sh/atomicity.h Some of this is probably related to the multiplicity of sh ISAs and the lack of a specific SH atomic-instructions-presence macro coordinated with a target_cpu value. For this, I blame sh or the gcc support of sh. However, it's not sh's fault that there isn't a better way to do this in libstdc++ and the file has to be duplicated. Sometimes I think that we should redo atomics config yet again to do the following: 1) compile-time check for atomic builtins, use if found 2) if not found, try one of the asm hacks, and *RUN* something with the found config to see if it actually works 3) if none of the above work, use the *SINGLE* generic code with mutexes And, all of these have to work for multilibs, and whatever weird thread config that is passed down. However, I'm a bit timid about doing this, since we really need compiler support for 2 so that we can determine what the arch is for real when doing multilibs. That, and I've thrashed the atomics config enough for one year while ending up very close to the same place I started. -- Summary: atomics config for sh is wierd Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: libstdc++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bkoz at gcc dot gnu dot org GCC host triplet: sh*-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29366
