Re: Storing 16bit values in upper part of 32bit registers
On 10/15/2009 08:56 AM, Richard Henderson wrote: On 10/15/2009 07:41 AM, Markus L wrote: However the IS is designed so that it is beneficial to to store 16bit values in the high part of the registers (rNh) and also the calling conventions that we want follow require 16bit values to be passed and returned in rNh. What would be the proper way make the compiler use the upper parts of these registers for the 16bit operands? This feature is going to be difficult, but not impossible, and unless your ISA has some really odd features I won't vouch for the code quality. You say you want to canonically represent HImode in the high-part of the register. Additionally, you'll have to represent QImode in the high-part (if not further in the high byte). You'll need to follow the mips port and define TRULY_NOOP_TRUNCATION and the associated truncMN2 patterns. If you do all this, you won't have to do anything with FUNCTION_VALUE etc at all. Sorry for a *way* *late* reply to this, but wouldn't it also work to model the register file as a set of 16-bit registers (since that's what you really have -- individually addressable 16-bit registers) and exclude SImode values from register pairs which are not aligned. Then one can simply prefer the high 16-bit registers to the low 16-bit registers in the register priority sequence. I'm assuming there is something wrong with this, but I'm kind of curious as to what it would be. -hpa

args aren't considered in partial ordering (14.6.6.2):
templatetypename T, typename... Args
int f(const T, Args...);
templatetypename T
float f(const T, double d = 2);
float g() {

[Bug c++/41959] New: Vector type name mangling is size ambiguous
---
#include x86intrin.h
void f(__m128) { }
void f(__m256) { }
---
Build with the -mavx flag to enable 32-byte vectors.
z.s: Assembler messages:
z.s:22: Error: symbol `_Z1fU8__vectorf' is already defined
This because the vector mangling does not include the size of the vector,
and thus __m128 and __m256 mangle to the same thing.

[Bug c++/41960] New: g++: friend introduce name into class, violate standard
below code cannot be compiled:
---
#define TYPEN::C
#define ASSIGN do {} while(0)
//#define ASSIGNdo { x-i = 0;} while(0)
//#define TYPE N::B
namespace N {
class B;
class C;
}

namespace N {
class B { int i; };
class C {
int i;
friend void func(TYPE * x);
};
}
void func(TYPE * x) { ASSIGN; }
int main()
{
TYPE x;
func(x);
return 0;
}
---
g++ report:
/test-cpp.cpp: In function 'int main()':
./test-cpp.cpp:22: error: call of overloaded 'func(N::C*)' is ambiguous
./test-cpp.cpp:18: note: candidates are: void func(N::C*)
./test-cpp.cpp:15: note: void N::func(N::C*)
change
#define TYPE N::C
to
#define TYPEN::B
then the code can be compiled.
According to [namespace.memdef] and [basic.scope.pdecl]:
---
friend declarations refer to functions or classes that are members of the
nearest enclosing namespace, but they do not introduce new names into that
namespace (7.3.1.2).
---
According to standard, ::func(N::C * x) shouldn't become friend of N::C, but
there should no ambiguous, because 'friend void func(TYPE * x);' look for
N::func(N::C *), and it doesn't exist at all. According to [namespace.memdef],
the names introduced by 'friend' is invisible until its real declaration.
It seems that, g++ wrongly introduces a name: N::func(N::C*) into namespace N,
and when calling func(N::C*), it follows koenig lookup and finds
N::func(N::C*). In the situation of 'friend void N::func(N::B*)', g++ works
correctly.

[basic.scope.local]:
Names declared in the for-init-statement, the for-range-declaration, and in the
condition of if, while, for, and switch statements are local to the if, while,
for, or switch statement (including the controlled statement), and shall not be
redeclared in a subsequent condition of that statement nor in the outermost
block (or, for the if statement, any of the outermost blocks) of the controlled
statement; see 6.4.
and:
[stmt.select]
[ Example:
if (int x = f()) {
int x; // ill-formed, redeclaration of x
}
else {
int x; // ill-formed, redeclaration of x
}
¡ªend example ]
However g++ compiles the example, without generating warning or error. -Wshadow
reports warning.
