[Bug c++/19076] New: Pointer to member function not matched
This is not a regression, but seems a serious problem, which, actually, is
blocking a simple implementation of various tr1/type_traits facilities :(
The following simplified testcase fails: for some reason, pointers to member
functions (vs, pointers to member objects) are not matched. ICC has no
problems at all with it.
//-
#include cassert
templatebool _Tv
struct integral_constant
{
static const bool value = _Tv;
};
typedef integral_constanttrue true_type;
typedef integral_constantfalsefalse_type;
templatetypename
struct is_member_pointer
: public false_type { };
templatetypename _Tp, typename _Cp
struct is_member_pointer_Tp _Cp::*
: public true_type { };
typedef void F();
struct S {};
typedef F S::*PMF;
int main()
{
assert( is_member_pointerPMF::value );
}

[Bug c/19078] New: [4.0 Regression] Poor quality code after loop unrolling.
The function:
int* find(int* a,int *b)
{
for(;a!=b;++a)
if(*a==2) return a;
return a;
}
Is unrolled in both 3.3 and 4.0 with -O2 -funroll-loops. The code from 4.0 is
however about twice as large, and seems to feature a large amount of unnessasary
rearranging of registers, and is somewhat slower.

[Bug preprocessor/19081] New: cpp merging operator ## literal in output
The macro #define PAYME(x) $##x in the code below gives output like roll $##7, %eax; after preprocessing with cpp (cpp md5block.spp md5block.s). Both version 2.95.3 on OpenBSD 3.6 and cpp (GCC) 3.3 20030304 (Apple Computer, Inc. build 1495) have been tested, and give the same type of error. With the macro changed to #define PAYME(x) $/**/x I get the desired output roll $7, %eax; but one would expect to get roll $ 7, %eax; (with whitespace). /**/ /* * rfc1321 requires that I include this.

[Bug rtl-optimization/19078] [4.0 Regression] Poor quality code after loop unrolling.
--- Additional Comments From rakdver at gcc dot gnu dot org 2004-12-19 19:41 --- Unroller splits the induction variables, so that the final code looks basically like if (a[0] == 2) return a; if (a[1] == 2) return a + 4; if (a[2] == 2) return a + 8; ... if (a[7] == 2) return a + 28; a+=32; Which is good in some cases, but obviously not here. However even with -fno-split-ivs-in-unroller we do not get the autoincrements; we also need -fno-ivopts. The reason is that with ivopts the code looks like a = a.1; a.1 = a + 1; if (*a == 2) return a; Whereas the old loop optimizer makes things look like a = a + 1 if (*a == 2) return 0; by changing the initial value of a, which enables the autoinc creation pass to work. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19078

Why not the minimal testcase:
-
template typename struct X;
templatetypename _Tp, typename _Cp struct X_Tp _Cp::* {};
typedef int F();
struct S { F f; };
typedef F S::*PMF;
XPMF s;
g/x c++ -c x.cc
x.cc:9: error: aggregate `Xint (S::*)() s' has incomplete type and cannot be
defined
x.cc:9: error: storage size of `s' isn't known
g/x icc -c x.cc
The problem is really that F is a reference to a function. If we define
the typedef as
typedef int F;
then everything is fine.

[Bug middle-end/18683] [4.0 Regression] seg fault in local allocate
--- Additional Comments From roger at eyesopen dot com 2004-12-19 23:51 --- This is perhaps the most bizarre interaction I've yet come across in GCC. Under normal operation, reg_renumber is zero prior to register allocation, then in rest_of_handle_old_regalloc, allocate_reg_info is called to allocate per-pseudo information, which is used two or three function calls later by local_alloc (and should remain valid for the remainder of the function's compilation). Unfortunately, between allocate_reg_info and local_alloc we call regclass which in this test case, unintentionally resets reg_renumber to zero! The incomplete and abridged call stack is reg_class - scan_one_insn - extract_insn - recog_23 - current_file_function_operand - make_decl_rtl - decl_assembler_name - mangle_decl - write_mangled_name - write_encoding - get_mostly_instantiated_function_type - pop_access_scope - pop_from_top_level - pop_context_function_from. In the middle of pop_context_function_from is the line reg_renumber = 0! This problem is either a (i) middle-end issue, (ii) an rs6000 backend issue, or (iii) a C++ front-end issue. (i) I don't think that pop_context_function_from should (or needs to) reset reg_renumber to zero. I would hope that with cgraph, there is only ever a single function being expanded to RTL at a time, so reg_renumber can be left as is. Certainly, if we're not saving the value of reg_renumber (and the arrays contents) in push_function_context_to, then we shouldn't attempt to restore it afterwards. I'm currently testing this fix. (ii) This interaction can also be avoided if the rs6000's function current_file_function_operand used DECL_RTL_SET_P to test whether an identifier is local to a function prior to checking the result of DECL_RTL. This avoids the invocation of make_decl_rtl. Presumably, if we don't know the assembler name for this function, we can't be calling it :) [I'll test this fix next]. (iii) The problem might well be in the C++ front-end and its interaction with cgraph. It's unclear whether DECL_RTL should already have been set on current_function_decl prior to this point in rest_of_compilation. Clearly, this only appears to happen for C++ templates, so the rs6000 backend is perhaps reasonable in assuming DECL_RTL has been set by this point. The above analysis also explains why enabling various tree dumps resolves the segmentation fault, as we end up calling/caching decl_assembler_name for the current function before reaching local register allocation (avoiding this particular interaction). This is probably fall-out from the recent cgraph/varasm reorganizations that attempt to avoid calling decl_assembler_name until as late as physically possible. Calling it for the first time before or after local alloc probably works fine, calling it during (as is done on rs6000 targets) has unanticipated side-effects. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18683
