* Improve auto-detection of "restrict" keywordeschnett2011-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | Update and improve the auto-detection of the "restrict" keyword; add more test cases to detect more possible failures. Disable testing the array syntax void foo (double A[restrict]); where the "restrict" keyword is given within the square brackets; instead, one can use the pointer syntax void foo (double *restrict const A); which is tested. Add support for the gcc built-in function "builtin_expect", which tells the compiler the value that an expression is most likely to have. Re-enable the (currently commented out) definitions for attribute(hot) and attribute(cold). git-svn-id: http://svn.cactuscode.org/flesh/trunk@4702 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Ian Hinder:knarf2011-02-01
| | | | | | | | | | | Cactus supports a variable OPTIMISE=yes/no to control whether optimisation is performed during compilation. Setting this variable to "yes" (for example, make sim-config OPTIMISE=yes) adds the flags in C_OPTIMISE_FLAGS to CFLAGS so that optimisation is performed. This is the default. Setting OPTIMISE=no does not add the flags. For gcc, this results in an unoptimised configuration as gcc assumes -O0 as the default. The Intel compiler, however, uses -O2 as the default. Hence, setting OPTIMISE=no has no effect on Intel, and -O2 is still used. This patch adds new configuration options C_NO_OPTIMISE_FLAGS, CXX_NO_OPTIMISE_FLAGS, F77_NO_OPTIMISE_FLAGS and F90_NO_OPTIMISE_FLAGS to complement the *_OPTIMISE_FLAGS options. These are added to the flags when OPTIMISE=no is used, and they default to -O0, which for the commonly used gcc and Intel compilers will lead to an unoptimised configuration. This requires a CONFIG-reconfig, but this is not enforced because this option doesn't affect most people, and failing to -reconfig is not fatal. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4681 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Introduce a new autoconf macro CCTK_CHECK_C_INLINE, which checks forschnetter2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | the inline keyword very similarly to AC_C_INLINE. CCTK_CHECK_C_INLINE works in the following way: Do nothing if the compiler accepts the inline keyword. Otherwise define inline to __inline__ or __inline if one of those work, otherwise define inline to be empty. The setting '__inline__ __attribute__((__gnu_inline__))' is for gcc 4.3 and later. By default this version of gcc follows the new ANSI standard for "static inline" and "extern inline", which is incompatible with many libraries (e.g. GSL), leading to linker errors about duplicate symbols. This is because "static inline" now generates an externally visible symbol. The setting above makes gcc fall back to the old meaning, which does not generate an externally visible symbol for "static inline". Use CCTK_CHECK_C_INLINE instead of AC_C_INLINE in configure.in.

* Cactus' autodetection of Fortran's real*16 does currently not work; itschnetter2006-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | always detects it as "not present", even if the message printed to the screen during configuration says "present". The enclosed patch corrects this: Rename the detecting autoconf macro from CCTK_PROG_FORTRAN_REAL16 to CCTK_FORTRAN_REAL16. This follows the usual autoconf naming conventions; see e.g. CCTK_CXX_BOOL. Also rename the return value (a global variable) from fortran_does_real16 to cctk_cv_have_fortran_real16. In this macro, use the function AC_TRY_COMPILE instead of AC_TRY_COMPILER. The difference is that this then only compiles, it does not try to link and execute. Executing would require handling cross-compiling in a special way. Replace the autoconf macro AC_TRY_COMPILE by CCTK_TRY_COMPILE, correcting an error in handling Fortran programmes. AC_TRY_COMPILE does not work for Fortran in autoconf 2.13. Move setting the compiler debug and warning flags further up in configure.in, so that the Fortran 77 compiler flags, which may be copied from the Fortran 90 compiler flags, are correct when the Fortran types are detected. Otherwise the wrong Fortran 77 compiler may be used for this test. Add autodetection for all the Fortran types real*4, real*8, real*16, complex*8, complex*16, and complex*32. Make this result available to thorns as HAVE_CCTK_FORTRAN_xxx. Define the CCTK_REALxxx and HAVE_CCTK_REALxxx macros only if the corresponding real and complex types are available in both C and Fortran. Remove some leftover debugging statements. Tested on Darwin-x86 with gcc and Linux-x86 with Intel. Touche force-reconfigure. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4351 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Add a new configuration flag PROFILE=yes, which enables profiling in aschnetter2006-06-23
| | | | | | | | | | | | | | | | | | | build. This flag is equivalent to OPTIMISE=yes and DEBUG=yes. Additional compiler options {C,CXX,F77,F90}_PROFILE_FLAGS are also introduced. The configuration stage sets the F77 flags to the F90 flags if an F90 compiler is found. This flag setting was done too early, namely before the default values for the F90 flags were set. This flag setting has been moved to a later time. The link command used undefined make variables $(OPTIMISE_C) etc. These variables have been removed. Instead $(CXX_OPTIMISE_FLAGS) etc. are added to the link statement. This makes the linker pick up the correct flags e.g. for profiling. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4327 17b73243-c579-4c4c-a9d2-2d5706c11dac
* Application of patchswhite2006-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fortran REAL*16 detection http://www.cactuscode.org/old/pipermail/patches/2006-April/000164.html ... a patch that makes Cactus directly detect Fortran support for a REAL*16 type. The problem has been that Cactus based CCTK_REAL16 on support for the C type 'long double'. This would cause it to create Fortran code for REAL*16, a type which was sometimes not supported. In particular, on a 64-bit Athlon machine with Gnu 4.1.0, gfortran defines REAL*8 but not REAL*16, while gcc defines 'long double'. This caused thorn AEIThorns/Fortran to fail to compile. This patch causes the configuration to directly compile Fortran code that features REAL*16, and define CCTK_REAL16 only if that compiles *and* C's 'long double' is supported. When you make config, you will see a new line about Fortran REAL*16. I have tested the enclosed patch on my laptop with Gnu 4.10 and Intel 9.0 compilers 64-bit AMD Athlon with same compilers POWER4 with IBM XL compilers BUT NOTE: I have severe doubts about using REAL*16 on any of these architectures. That 16-byte (128-bit) type is not natively supported on the Xeon, Athlon, or POWER machines. While some compilers support such types, calculation is done in software, not on the FPU. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4314 17b73243-c579-4c4c-a9d2-2d5706c11dac
