Wed Jan 29 12:14:19 1997 Andrew Cagney * The code to allow an event queue to be updated during a signal was missing.

Fri Jul 26 00:36:35 1996 Andrew Cagney * ppc-cache-rules (cache): Change RS and RB to cache instead of compute.

(HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure. Mon Jul 22 22:38:59 1996 Andrew Cagney * psim.c (psim_options): Enter the argument to the memory size option directly into the device tree. Was using atol() which is dangerously non portable. Mon Jul 22 22:17:08 1996 Andrew Cagney * configure.in (icache): Extend icache flag to include an insn option. If specifyed the insn - aka instruction - is included in the instruction cache.

The CPP line directives would have previously set the line-nr and file name so ITRACE isn't needed. Sun Jul 21 21:18:05 1996 Andrew Cagney * gen-idecode.c (print_jump_until_stop_body): New function and idecode generation option. Instead of generating and calling separate functions containing the semantic and icache code generate a single monolythic function and use goto's (and GCC's indirect jump) to move between code blocks. * Makefile.in: Add sim_jump flag to those passed to igen. * configure.in: New option --enable-sim-jump (default disabled) * ppc-instructions: Eliminate any uses of labels and goto's.
