Werner Almesberger	65a8578bd2	ubb-la/Makefile: add SDL (may break "static")	2013-01-30 21:19:09 -03:00
Werner Almesberger	09de2454ef	ubb-la/Makefile (CFLAGS): use more specific -O9 -fno-tree-cselim ... Third time lucky, I hope. -fno-tree-cselim is much more specific than disabling all optimization and results in a considerably less severe performance reduction (about 30-40% of -O0).	2013-01-25 19:49:20 -03:00
Werner Almesberger	bac21bf8cb	ubb-la/Makefile (CFLAGS): even -O1 isn't safe; use -O0 instead ... While -O1 gets rid of the unexpected read in the simple code of a synthetic test, it's still there in the more complex environment we have in ubb-la.c Turning off optimization completely seems to do the trick.	2013-01-24 17:35:52 -03:00
Werner Almesberger	e1eea4fa86	ubb-la/Makefile (CFLAGS): -O9 is currently unsafe; use -O1 ... Higher optimizations can cause the generation of code that unexpectedly does the equivalent of PDFUNS = PDFUNS; http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56098	2013-01-24 15:31:59 -03:00
Werner Almesberger	2c5b3625a7	ubb-la/: data capture via UBB and MSC+DMA (WIP)	2013-01-23 11:54:23 -03:00
