From Revision 3025 to 3006

Rev	Summary	Authors	Tags	Date
3025	fftw-mpi.h should include <fftw3.h>, not "fftw3.h" fftw-mpi.h should include <fftw3.h>, not "fftw3.h"	Matteo Frigo	fftw-3.3.7, fftw-3.3.7-rc2	6 years ago

3023	Update NEWS for upcoming fftw-3.3.7 Update NEWS for upcoming fftw-3.3.7	Matteo Frigo	fftw-3.3.7-rc1	6 years ago
3022	Ditch --enable-debug-malloc and --enable-debug-alignment Ditch --enable-debug-malloc and --enable-debug-alignment We wrote DEBUG_MALLOC in 1997 to debug memory leaks. Nowadays DEBUG_MALLOC is just confusing. Better tools are available, and DEBUG_MALLOC is not thread-safe and it does not respect SIMD alignment. It confused at least one user. In the gcc-2.SOMETHING days, gcc would allocate doubles on the stack at 4-byte boundary (vs. 8) reducing performance by a factor of 3. That's when we introduced --enable-debug-alignment, which is totally obsolete by now.	Matteo Frigo		6 years ago
3021	Use armv7a cycle counter unconditionally if HAVE_ARMV7A_CNTV... Use armv7a cycle counter unconditionally if HAVE_ARMV7A_CNTVCT It looks like __ARM_ARCH_7A__ is not always defined. If the user says HAVE_ARMV7A_CNTVCT, trust the user.	Matteo Frigo		6 years ago
3020	Merge pull request #110 from junghans/cmake Merge pull request #110 from junghans/cmake Minor cmake fixes	Matteo Frigo		6 years ago
3019	simd-vsx.h: don't use vpermxor simd-vsx.h: don't use vpermxor It seems like gcc-6 generates incorrect code when using vpermxor (tested with qemu emulator, so there is a chance that gcc is right and qemu is wrong). Disable the use of vpermxor and do the simple thing (one multiplication + one permutation).	Matteo Frigo		6 years ago
3018	Remove AC_FUNC_{MALLOC,REALLOC,MMAP} Remove AC_FUNC_{MALLOC,REALLOC,MMAP} They don't do what I thought. E.g., AC_FUNC_MALLOC checks that malloc(0) returns NULL, and defines malloc to be rpl_malloc otherwise. We don't support rpl_malloc() and we don't care about malloc(0).	Matteo Frigo		6 years ago
3017	Dead-Code Police Dead-Code Police	Matteo Frigo		6 years ago
3016	Fixup fftw3-mpi.h Fixup fftw3-mpi.h fftw3-mpi.h must include "fftw3.h", not "api/fftw3.h", because both fftw3-mpi.h and fftw3.h will ultimately be installed in /usr/include. Thus, as a special exception, mpi/Makefile.am must specify the include path -I $(top_srcdir)/api.	Matteo Frigo		6 years ago
3015	Generate codlist.c only when MAINTAINER_MODE Generate codlist.c only when MAINTAINER_MODE The user is not supposed to regenerate .c files. In addition, the generation rule is subtly nonportable (it depends on whether or not '#' can be escaped in Makefiles, an issue that does not appear settled.)	Matteo Frigo		6 years ago
3014	Generate {dft,rdft}/simd/{sse,sse2,avx,...}/.c only when MA... Generate {dft,rdft}/simd/{sse,sse2,avx,...}/.c only when MAINTAINER_MODE Users are not supposed to generate them. Apart from that, the generation rule uses '$*' in an explicit make rule, which is technically a GNU extension. (Works with {open,free}bsd, but breaks Solaris.)	Matteo Frigo		6 years ago
3013	Restore the ability to build out of tree. Restore the ability to build out of tree. Before 1f3704b9, we had "-I $(top_srcdir)/foo -I $(top_srcdir)/bar". After 1f3704b9, we had no -I specification at all, but automake wants an explicit -I $(top_srcdir) in order to build out of tree.	Matteo Frigo		6 years ago
3012	Merge pull request #107 from xantares/config-mode Merge pull request #107 from xantares/config-mode Config mode	Matteo Frigo		6 years ago
3011	Fix performance regression with gcc-3.3 Fix performance regression with gcc-3.3	Matteo Frigo		6 years ago
3010	get rid of the sse2-nonportable.c hack get rid of the sse2-nonportable.c hack It was necessary to support some broken compiler 15 years ago. Remove it and see if anybody complains.	Matteo Frigo		6 years ago
3009	configure.ac Police configure.ac Police Remove some obsolete AC_CHECK_HEADERS, add new checks suggested by autoscan.	Matteo Frigo		6 years ago
3008	Include Police Include Police fftw-wisdom.c was including <fftw3.h> instead of "api/fftw3.h"	Matteo Frigo		6 years ago
3007	Do not set include path ("-I") in Makefile.am Do not set include path ("-I") in Makefile.am .[ch] files should specify their own paths explicitly. Setting paths in the Makefile was always a bad idea, but it is totally untenable if we are supporting cmake.	Matteo Frigo		6 years ago
3006	Fix OpenBSD build Fix OpenBSD build Using $< in a non-suffix rule context is a GNUmake idiom and OpenBSD doesn't like it.	Matteo Frigo		6 years ago
