Since all defintion is in the .h file and all functions are inline functions, it may be a problem.(See http://gcc.gnu.org/faq.html#vtables).

[Bug c++/36797] ICE on SFINAE and __is_empty
--- Comment #5 from paolo dot carlini at oracle dot com 2008-07-14 09:15 --- (In reply to comment #4) I think the first thing is to figure out what mangling we want for these things and if they should be mangled at all. The C++ ABI doesn't specify a mangling for these operators, since it doesn't specify these operators at all. They're really an implementation detail. So, the first question is Do these operators need to appear in mangled names at all? Is it a reasonable restriction on users to say thou shalt not use __is_empty in an expression that gets mangled? For example, can the user just use std::is_empty instead? Thanks for your feedback, Mark. Frankly, at the moment I don't have a strong opinion, but I'm wondering if existing practice can help us about those points: in fact such builtins are modeled after the existing Microsoft builtins: http://msdn.microsoft.com/de-de/library/ms177194.aspx and probably knowing what Microsoft is doing could help... However, I don't think Visual c++ uses our multivendor ABI, thus I'm not sure investigating that point could suggest a specific mangling. What do you think? (well, in case we are going to need help from people owning a recent Visual C++...) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36797
[Bug fortran/36821] New: Flush denormals to Zero Flag
On current x86 and x86_64 processors denormal numbers are handled as a special case and very slowly. This can have a detrimental impact on the performance of numerical programs. A common fix for this problem, at the cost of some numerical stability, is to set the processor flag to flush denormals to zero. This can be achieved in C with the following on SSE machines: _MM_SET_FLUSH_ZERO_MODE (_MM_FLUSH_ZERO_ON); However it is not desirable to include C in a fortran program or library. Other compiler tackle this by adding flags (ifort, NAG f95) or environment variables (g95) which set this flush mode during program initialization. It would be good if gfortran offered a similar facility (I have not been able to locate any reference to one at the moment). -- Summary: Flush denormals to Zero Flag Product: gcc Version: 4.3.1 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: J dot Hogg at rl dot ac dot uk http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36821

[Bug fortran/36771] Non-Standard addition for C_LOC and character strings
--- Comment #1 from brtnfld at hdfgroup dot org 2008-07-14 20:45 --- For the simple program, PROGRAM main USE ISO_C_BINDING CHARACTER(LEN=2, KIND=C_CHAR), TARGET :: chr TYPE(C_PTR) :: chr_ptr chr_ptr = C_LOC(chr) END PROGRAM main the work around is to: CHARACTER(LEN=1, KIND=C_CHAR), dimension(1:2), TARGET :: chr However, forcing it to be an array instead of a character(LEN1) causes problems with generic interfaces. Take for example the following code which to me looks to be standard compliant, via the standard the CHARACTER(LEN=4) actual argument is allowed to match a CHARACTER(LEN=1,KIND=C_CHAR), DIMENSION(4) dummy argument (12.4.1.2). But the compiler will not recognize subroutine 'Two' as a valid interface for the call indicated since the dimensions check is not satisfied even though it is a valid interface. So if you are going by the standard you can not use a generic interface to handle a scalar character (len1) and an array of characters (keeping in mind that all the subroutines have to have LEN=1 so that you can use C_LOC). MODULE modtest USE ISO_C_BINDING INTERFACE One MODULE PROCEDURE Two END INTERFACE CONTAINS SUBROUTINE Two( chr ) CHARACTER(LEN=1, KIND=C_CHAR), DIMENSION(1:4) :: chr END SUBROUTINE Two END MODULE modtest PROGRAM main USE ISO_C_BINDING USE modtest CHARACTER(LEN=4, KIND=C_CHAR) :: chrScalar chrScalar = 'Scal' ! This does not work, it will not find the interface. CALL One( chrScalar ) ! This works CALL Two( chrScalar ) END PROGRAM main It is simply not feasible to cast all character strings into character arrays. This problem would all go away if we did not have to recast the string as an array. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36771
