[Bug target/55351] can't build libgcc for -m5-compact variant in SH64
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55351 --- Comment #3 from Dan Horák dan at danny dot cz 2012-11-20 15:15:50 UTC --- (In reply to comment #2) The first hunk of the patch that adds: MULTILIB_EXCEPTIONS = *m5-64media* *m5-64media-nofpu* to gcc/config/sh/t-linux causes the sh-linux-gnu build to fail. Commenting out this line allows both sh- and sh64-linux-gnu to build. I guess there is a conflict with the ! values in --with-multilib-list=m1,m2,m2e,m4,m4-single,m4-single-only,m2a,m2a-single,!m2a,!m2a-single passed to the sh-linux compiler

[Bug c++/28631] New: no candidate even when it exists, depends on position of the function
I have a code (usage of C++ binding for the Squirrel language in the
Code::Blocks IDE) that cannot be compiled with g++ from 4.1.1 (from FC devel)
and 4.2.0 (20060729), but can be compiled with 3.2, 3.4 and 4.0 (all on
Redhat/Fedora).
The output from the compiler is
--
scriptbindings.cc: In static member function static void
SqPlus::ReturnSpecializationRT::Call(Callee, RT (Callee::*)(P1)const) [with
Callee = Base, P1 = const String, RT = const String]:
scriptbindings.cc:55: instantiated from void SqPlus::Call(Callee, RT
(Callee::*)(P1)const) [with Callee = Base, RT = const String, P1 = const
String]
scriptbindings.cc:60: instantiated from void
SqPlus::RegisterInstance(Callee, Func) [with Callee = Base, Func = const
String (Base::*)(const String)const]
scriptbindings.cc:69: instantiated from SqPlus::SQClassDefTClassType
SqPlus::SQClassDefTClassType::func(Func) [with Func = const String
(Base::*)(const String)const, TClassType = Base]
scriptbindings.cc:84: instantiated from here
scriptbindings.cc:44: error: no matching function for call to Push(const
String)
scriptbindings.cc:27: note: candidates are: void SqPlus::Push(bool)
scriptbindings.cc:30: note: void SqPlus::Push(int)
--
It compiles when
- I remove the SqPlus namespace
- move the Push(bool) and Push(int) down to the definition of Push(String)
- move the Push(String) up to the Push(bool) and Push(int)
The code is here (downsized from 80K+ lines and 2+ MB :-) )
class String
{
public:
String();
};
class Base
{
public:
Base();
const String GetString(const String key) const;
bool GetBool() const;
};
namespace SqPlus {
templateclass T
struct TypeWrapper {
};
templatetypename T
T * GetInstance() {
return (T *)0;
}
inline void Push(bool value) { }
inline bool Get(TypeWrapperbool) { return *GetInstancebool(); }
inline void Push(int value) { }
templateclass RT
struct ReturnSpecialization {
template typename Callee
static void Call(Callee callee,RT (Callee::*func)() const) {
RT ret = (callee.*func)();
Push(ret);
}
template typename Callee,typename P1
static void Call(Callee callee,RT (Callee::*func)(P1) const)
{
RT ret = (callee.*func)(Get(TypeWrapperP1()));
Push(ret);
}
};
templatetypename Callee,typename RT
void Call(Callee callee, RT (Callee::*func)() const) {
ReturnSpecializationRT::Call(callee,func);
}
templatetypename Callee,typename RT,typename P1
void Call(Callee callee,RT (Callee::*func)(P1) const) {
ReturnSpecializationRT::Call(callee,func);
}
templatetypename Callee,typename Func
inline void RegisterInstance(Callee callee,Func func) {
Call(*(Callee *)0,*(Func *)0);
}
templatetypename TClassType
struct SQClassDef {
SQClassDef();
templatetypename Func
SQClassDef func(Func pfunc) {
RegisterInstance(*(TClassType *)0,pfunc);
return *this;
}
};
inline void Push(const String value) { }
inline const String Get(TypeWrapperconst String ) { return
*GetInstanceString(); }
inline void Push(Base * value) { }
inline Base Get(TypeWrapperBase ) { return *GetInstanceBase(); }
};
void RegisterBindings()
{
SqPlus::SQClassDefBase().
func(Base::GetString).
func(Base::GetBool);
}
