From 17508d02bba1d47f4cf884b190566e72f69adb4e Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Wed, 26 Jul 2000 19:26:28 +0000 Subject: Port of RTEMS to the Texas Instruments C3x/C4x DSP families including a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4. --- c/src/lib/libbsp/c4x/c4xsim/.cvsignore | 13 +++++++++++++ c/src/lib/libbsp/c4x/c4xsim/clock/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/console/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/console/Makefile.am | 2 +- c/src/lib/libbsp/c4x/c4xsim/include/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/include/Makefile.am | 5 +---- c/src/lib/libbsp/c4x/c4xsim/start/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/startup/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/startup/bspstart.c | 15 --------------- c/src/lib/libbsp/c4x/c4xsim/timer/.cvsignore | 2 ++ c/src/lib/libbsp/c4x/c4xsim/tools/.cvsignore | 2 ++ 11 files changed, 29 insertions(+), 20 deletions(-) create mode 100644 c/src/lib/libbsp/c4x/c4xsim/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/clock/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/console/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/include/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/start/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/startup/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/timer/.cvsignore create mode 100644 c/src/lib/libbsp/c4x/c4xsim/tools/.cvsignore (limited to 'c/src/lib/libbsp/c4x/c4xsim') diff --git a/c/src/lib/libbsp/c4x/c4xsim/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/.cvsignore new file mode 100644 index 0000000000..525275c115 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/.cvsignore @@ -0,0 +1,13 @@ +Makefile +Makefile.in +aclocal.m4 +config.cache +config.guess +config.log +config.status +config.sub +configure +depcomp +install-sh +missing +mkinstalldirs diff --git a/c/src/lib/libbsp/c4x/c4xsim/clock/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/clock/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/clock/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/c/src/lib/libbsp/c4x/c4xsim/console/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/console/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/console/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/c/src/lib/libbsp/c4x/c4xsim/console/Makefile.am b/c/src/lib/libbsp/c4x/c4xsim/console/Makefile.am index b05928ea32..50545f9ed9 100644 --- a/c/src/lib/libbsp/c4x/c4xsim/console/Makefile.am +++ b/c/src/lib/libbsp/c4x/c4xsim/console/Makefile.am @@ -8,7 +8,7 @@ PGM = $(ARCH)/console.rel VPATH = @srcdir@:@srcdir@/../../../shared -C_FILES = console.c consolereserveresources.c debugio.c simio.c printk.c +C_FILES = console.c consolereserveresources.c debugio.c simio.c C_O_FILES = $(C_FILES:%.c=$(ARCH)/%.o) OBJS = $(C_O_FILES) diff --git a/c/src/lib/libbsp/c4x/c4xsim/include/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/include/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/include/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/c/src/lib/libbsp/c4x/c4xsim/include/Makefile.am b/c/src/lib/libbsp/c4x/c4xsim/include/Makefile.am index ffaffc58e4..39708ee467 100644 --- a/c/src/lib/libbsp/c4x/c4xsim/include/Makefile.am +++ b/c/src/lib/libbsp/c4x/c4xsim/include/Makefile.am @@ -12,14 +12,11 @@ $(PROJECT_INCLUDE): $(PROJECT_INCLUDE)/%.h: %.h $(INSTALL_DATA) $< $@ -$(PROJECT_INCLUDE)/bspIo.h: $(top_srcdir)/../../shared/include/bspIo.h - $(INSTALL_DATA) $< $@ - $(PROJECT_INCLUDE)/coverhd.h: $(top_srcdir)/../../shared/include/coverhd.h $(INSTALL_DATA) $< $@ PREINSTALL_FILES += $(PROJECT_INCLUDE) $(H_FILES:%.h=$(PROJECT_INCLUDE)/%.h) \ - $(PROJECT_INCLUDE)/bspIo.h $(PROJECT_INCLUDE)/coverhd.h + $(PROJECT_INCLUDE)/coverhd.h all-local: $(PREINSTALL_FILES) diff --git a/c/src/lib/libbsp/c4x/c4xsim/start/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/start/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/start/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/c/src/lib/libbsp/c4x/c4xsim/startup/.cvsignore b/c/src/lib/libbsp/c4x/c4xsim/startup/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/c/src/lib/libbsp/c4x/c4xsim/startup/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/c/src/lib/libbsp/c4x/c4xsim/startup/bspstart.c b/c/src/lib/libbsp/c4x/c4xsim/startup/bspstart.c index 34adabdc48..5e73a2034c 100644 --- a/c/src/lib/libbsp/c4x/c4xsim/startup/bspstart.c +++ b/c/src/lib/libbsp/c4x/c4xsim/startup/bspstart.c @@ -104,21 +104,6 @@ void bsp_start( void ) if ( BSP_Configuration.work_space_size > (int) &_WorkspaceMax ) rtems_fatal_error_occurred( 0x43218765 );
