From 189e2694ad699b902669c1bc4b3c0112223d3282 Mon Sep 17 00:00:00 2001 From: Doug Evans Date: Mon, 19 Jan 1998 21:14:14 +0000 Subject: [PATCH] * Make-common.in (cgen-{arch,cpu,decode}): New targets. * cgen.sh: New file. * cgen-scache.h: Deleted. * cgen-scache.c: Only compile contents if WITH_SCACHE. (scache_init): Use runtime computed size of SCACHE. (scache_flush): Likewise. * cgen-mem.h (GETIMEMU[QHSD]I): Declare. ([GS]ETT{QI,UQI,HI,UHI,SI,USI,DI,UDI}): Declare. * cgen-sim.h: Scache support moved here. (PC): Redo definition. (ARGBUF,SCACHE,PARALLEL_EXEC): Provide forward decls. (DECODE): Add parallel execution support. Only include semantic label members if using switch. (SWITCH,CASE,BREAK,DEFAULT,ENDSWITCH): Portable computed goto support. (CGEN_CPU): Delete members exec_state, halt_sigrc, halt_jmp_buf. (IADDR,CIA,SEM_ARG,EX_FN_NAME,SEM_FN_NAME,RECORD_IADDR,SEM_ARGBUF, SEM_NEXT_PC,SEM_BRANCH_VIA_{CACHE,ADDR},SEM_NEW_PC_ADDR): Moved here from cgen-types.h. (engine_{stop,run,resume,halt,signal}): Delete decls. * cgen-types.h (CGEN_{XCAT3,CAT3}): Delete. (argbuf,scache): Delete forward decls. (STATE): Delete decl. * cgen-utils.c: Don't include decode.h, mem-ops.h, sem-ops.h. Include cgen-mem.h, cgen-ops.h. (engine_halt,engine_signal): Delete. ({ex,exc,sem,semc}_illegal): Delete. (sim_disassemble_insn): Result of extract fn is in bits. * genmloop.sh: Rewrite. --- sim/common/.Sanitize | 2 +- sim/common/ChangeLog | 44 ++++++++++++++ sim/common/Make-common.in | 52 +++++++++++++++- sim/common/cgen.sh | 125 ++++++++++++++++++++++++++++++++++++++ 4 files changed, 220 insertions(+), 3 deletions(-) create mode 100644 sim/common/cgen.sh diff --git a/sim/common/.Sanitize b/sim/common/.Sanitize index 34907155726..fc5d1796104 100644 --- a/sim/common/.Sanitize +++ b/sim/common/.Sanitize @@ -28,10 +28,10 @@ Make-common.in Makefile.in aclocal.m4 callback.c +cgen.sh cgen-mem.h cgen-ops.h cgen-scache.c -cgen-scache.h cgen-sim.h cgen-trace.c cgen-trace.h diff --git a/sim/common/ChangeLog b/sim/common/ChangeLog index acfabaeb9d6..59408c362d0 100644 --- a/sim/common/ChangeLog +++ b/sim/common/ChangeLog @@ -1,3 +1,47 @@ +Mon Jan 19 12:45:45 1998 Doug Evans + + * Make-common.in (cgen-{arch,cpu,decode}): New targets. + * cgen.sh: New file. + * cgen-scache.h: Deleted. + * cgen-scache.c: Only compile contents if WITH_SCACHE. + (scache_init): Use runtime computed size of SCACHE. + (scache_flush): Likewise. + * cgen-mem.h (GETIMEMU[QHSD]I): Declare. + ([GS]ETT{QI,UQI,HI,UHI,SI,USI,DI,UDI}): Declare. + * cgen-sim.h: Scache support moved here. + (PC): Redo definition. + (ARGBUF,SCACHE,PARALLEL_EXEC): Provide forward decls. + (DECODE): Add parallel execution support. + Only include semantic label members if using switch. + (SWITCH,CASE,BREAK,DEFAULT,ENDSWITCH): Portable computed goto support. + (CGEN_CPU): Delete members exec_state, halt_sigrc, halt_jmp_buf. + (IADDR,CIA,SEM_ARG,EX_FN_NAME,SEM_FN_NAME,RECORD_IADDR,SEM_ARGBUF, + SEM_NEXT_PC,SEM_BRANCH_VIA_{CACHE,ADDR},SEM_NEW_PC_ADDR): Moved here + from cgen-types.h. + (engine_{stop,run,resume,halt,signal}): Delete decls. + * cgen-types.h (CGEN_{XCAT3,CAT3}): Delete. + (argbuf,scache): Delete forward decls. + (STATE): Delete decl. + * cgen-utils.c: Don't include decode.h, mem-ops.h, sem-ops.h. + Include cgen-mem.h, cgen-ops.h. + (engine_halt,engine_signal): Delete. + ({ex,exc,sem,semc}_illegal): Delete. + (sim_disassemble_insn): Result of extract fn is in bits. + * genmloop.sh: Rewrite. + + * cgen-trace.c (trace_insn): Set printed_result_p=0 if not tracing + line numbers. + + * sim-base.h (sim_state_base): Delete member `model'. + (sim_cpu_base): Add member `model'. + * sim-model.h (IMP_PROPERTIES): New type. + (MACH): New members imp_props, models. + (models): Delete decl. + * sim-model.c (set_model): Update. + * sim-profile.c (profile_print_model): Update. + + * sim-utils.c (sim_state_alloc): Delete setting of cpu backlink here. + Fri Jan 16 12:33:09 1998 Nick Clifton * cgen-trace.c (trace_insn): Call CGEN_INSN_MNEMONIC() rather than diff --git a/sim/common/Make-common.in b/sim/common/Make-common.in index fb1cf8f5db0..9ed1bb3fd15 100644 --- a/sim/common/Make-common.in +++ b/sim/common/Make-common.in @@ -300,10 +300,11 @@ sim-bits.o: $(srccom)/sim-bits.c $(sim-bits_h) $(sim-n-bits_h) \ $(CC) -c $(srccom)/sim-bits.c $(ALL_CFLAGS) sim-config.o: $(srccom)/sim-config.c $(sim-config_h) \ - $(SIM_EXTRA_DEPS) + $(SIM_EXTRA_DEPS) $(CC) -c $(srccom)/sim-config.c $(ALL_CFLAGS) -sim-core.o: $(srccom)/sim-core.c $(sim-core_h) $(sim-n-core_h) \ +sim-core.o: $(srccom)/sim-core.c $(sim_main_headers) \ + $(sim-core_h) $(sim-n-core_h) \ $(SIM_EXTRA_DEPS) $(CC) -c $(srccom)/sim-core.c $(ALL_CFLAGS) @@ -478,4 +479,51 @@ stamp-h: config.in config.status .gdbinit: # config.status $(srccom)/gdbinit.in CONFIG_FILES=$@:../common/gdbinit.in CONFIG_HEADERS= $(SHELL) ./config.status +# CGEN support + +SCHEME = @SCHEME@ +SCHEME = guile-ss +SCHEME = guile +#SCHEMEFLAGS = -b +SCHEMEFLAGS = -s +srccgen = $(srcroot)/cgen + +CGEN_VERBOSE = -v +CGEN_MAIN_SCM = $(srccgen)/object.scm \ + $(srccgen)/utils.scm $(srccgen)/utils-cgen.scm \ + $(srccgen)/mode.scm \ + $(srccgen)/cpu.scm $(srccgen)/mach.scm \ + $(srccgen)/ifield.scm $(srccgen)/iformat.scm \ + $(srccgen)/operand.scm $(srccgen)/insn.scm \ + $(srccgen)/sim.scm +CGEN_CPU_SCM = $(srccgen)/sim-cpu.scm $(srccgen)/sem-ccode.scm +CGEN_DECODE_SCM = $(srccgen)/decode.scm + +# Various choices for which cpu specific files to generate. +CGEN_CPU_EXTR = -E tmp-ext.c1 +CGEN_CPU_READ = -R tmp-read.c1 +CGEN_CPU_SEM = -S tmp-sem.c1 +CGEN_CPU_SEMSW = -W tmp-semsw.c1 + +# We store the generated files in the source directory until we decide to +# ship a Scheme interpreter with gdb/binutils.
