There is support for the LEON3 processor available in Binutils 2.24 and the GCC 4.8 branch and GCC mainline.
GCC 4.8 branch: http://gcc.gnu.org/viewcvs/gcc/branches/?view=log&pathrev=205331 GCC mainline: http://gcc.gnu.org/viewcvs/gcc/trunk/?view=log&pathrev=202664 This is critical for further SMP development on LEON3 since it enables usage of C11 atomic operations. It makes it also possible to use an inline function for _CPU_SMP_Get_current_processor() which avoids the function call overhead in critical sections. --- c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg b/c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg index 58f2f07..34ad967 100644 --- a/c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg +++ b/c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg @@ -9,7 +9,7 @@ RTEMS_CPU_MODEL=leon3 # This contains the compiler options necessary to select the CPU model # and (hopefully) optimize for it. -CPU_CFLAGS = -mcpu=cypress -msoft-float +CPU_CFLAGS = -mcpu=leon3 -msoft-float # optimize flag: typically -O2 CFLAGS_OPTIMIZE_V = -O2 -g -- 1.7.7 _______________________________________________ rtems-devel mailing list rtems-devel@rtems.org http://www.rtems.org/mailman/listinfo/rtems-devel
