* 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

* Reorder CUDA makefile ruleseschnett2011-04-22
| | | | | | | | | The rules to build CUDA source files are very similar to those for C and C++, and different from those for the Fortran. Reorder reorder these makefile rules to make the code easier to understand. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4700 17b73243-c579-4c4c-a9d2-2d5706c11dac

* f_file_processor.pl: Fix handling of continuation lines with OpenMPhinder2011-04-11
| | | | | | | | | | | | | | | | | | | | | | OpenMP requires continuation lines in Fortran 90 (and possibly Fortran 77 as well though I have not checked that) to start with the OMP sentinel (https://computing.llnl.gov/tutorials/openMP/#Directives). This patch ensures that a sentinel OMP or HPF is repeated when a line starting with that sentinel is broken to limit its length to 132 characters. It also adds a case-insensitive flag to the check for "!" like comments and adds extra backslashes to the standard_comments regex to properly match $OMP after all metacharacters have been handled. Tested with LoopControl's Fortran interface on gcc 4.5,Intel 11.1 and PGI. (Patch by Roland Haas) git-svn-id: http://svn.cactuscode.org/flesh/trunk@4697 17b73243-c579-4c4c-a9d2-2d5706c11dac

It was not capable of detecting end of file (i.e. when $data->[$line_number] became undefined). I added checks to ensure $data->[$Line_number] was defined in two additional while loops.

* 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 commit adds the corresponding documentation to the UsersGuide. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4682 17b73243-c579-4c4c-a9d2-2d5706c11dac

| | | | | | | | | | | | | | | Correctly load parameter files with DOS line-endings Before this commit, when a parameter file with DOS line-endings was used, certain features of Cactus did not work correctly. For example, setting an output directory of $parfile would create an output directory named "$parfile" instead of expanding the parameter filename. This commit converts any CR-LF sequences to LF immediately after the parameter file is loaded. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4663 17b73243-c579-4c4c-a9d2-2d5706c11dac

* Improve optional requirement of capabilitieseschnett2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Thorns can specify that they can make use of a particular capability (for example HDF5), but that it is not absolutely required. It is currently not possible to detect a capability in the source code or make system of a thorn because there is no preprocessor macro and no make variable defined to indicate that the capability is available. Additionally, the preprocessor definitions which are explicitly provided by a capability are written to an include file which is malformed and hence these definitions cannot be read. This commit: * Introduces makefile and preprocessor variables HAVE_CAPABILITY_<cap> for each provided capability * Removes the incorrect definition line causing the include file to be malformed * Renames cctki_Capabilities.h to cctk_Capabilities.h and causes cctk_Capabilities.h to be included from cctk.h by all thorns * Excludes cctk_Capabilities.h from dependency checking (dependencies of the files included from this one will be sufficient) [Patch from Ian Hinder] git-svn-id: http://svn.cactuscode.org/flesh/trunk@4659 17b73243-c579-4c4c-a9d2-2d5706c11dac
