* compile.c (sim_resume): Make sure that dst.reg refers to the
right register byte in mova/sz.l @(dd,RnL),ERn.
2003-07-21 Richard Sandiford <rsandifo@redhat.com>
* compile.c (sim_resume): Zero-extend immediate to muls, mulsu,
mulxs, divs and divxs.
sim/testsuite/sim/h8300/ChangeLog:
2003-07-22 Michael Snyder <msnyder@redhat.com>
* mul.s: Don't try to use negative immediate (it's always
unsigned).
* div.s: Ditto.
* h8300/compile.c : Addition of extern variable h8300_normal_mode
(SP) : Handle normal mode
(bitfrom) : Use normal mode flag to return suitable value
(lvalue) : Use normal mode flag to return command line location
(decode) : Decode instruction correctly for normal mode
(init_pointers) : Initialise memory correctly for normal mode
(sim_resume) : Handle cases for normal mode using h8300_normal_mode flag
(sim_store_register) : Handle 2 byte PC for normal mode
(sim_fetch_register) : Handle 2 byte PC for normal mode
(set_h8300h) : Set normal mode flag as per architechture
(sim_load) : Allocate 64K for normal mode instead of bigger memory
* compile.c (decode): Enhancements for mova.
Initialize cst, reg, and rdisp inside the loop, for each
new instruction. Defer correction of the disp2 values until
later, and then adjust them by the size of the first operand,
rather than the size of the instruction.
(sim_resume): For mova, adjust the size of the second operand
according to the type of the first operand (INDEXB vs. INDEXW).
In cases where there is only one operand, the other two must
both be composed on the fly.
* compile.c: Replace "Hitachi" with "Renesas".
(decode): Distinguish AV_H8S from AV_H8H.
(sim_resume): H8SX can use any register for TAS.
(decode): Add support for VECIND.
(sim_resume): Implement rte/l and rts/l.
(GETSR): New macro (actually old macro reincarnated).
(decode): Add handling for IMM2.
(sim_resume): Drop extra block around jmp, jsr, rts.
Add handling for trapa and rte.
For divxu.b, change 0xffff mask to 0xff.
(set_h8300h): Add bfd_mach_h8300sxn machine.
* compile.c (sim_info): Fix typo in output.
* h8300/compile.c (set_h8300h): Replace 'flag' arguments
with a bfd_machine argument, and decode it inline.
Check for bfd_mach_h8300hn and bfd_mach_h8300sn.
2003-03-20 D.Venkatasubramanian <dvenkat@noida.hcltech.com>
* compile.c (cmdline_location): Added function to
return the location of 8-bit (256 locations) where the
Command Line arguments would be stored.
(decode): Added a TRAP to 0xcc for Commandline
processing using pseudo opcode O_SYS_CMDLINE.
(sim_resume): Added handling of O_SYS_CMDLINE Trap.
(sim_create_inferior): Setting a pointer to
Commandline Args array.
* inst.h: Added a new variable ptr_command_line for
storing pointer to Commandline array.
2003-03-14 D.Venkatasubramanian <dvenkat@noida.hcltech.com>
* compile.c (decode): Added code for some more magic traps.
* compile.c (sim_resume): Added support for File I/O system
calls through callback to host_system.
System calls provided support for :
open, read, write, lseek, close, stat, fstat
Only basic support for stat and fstat.
2000-06-20 Frank Ch. Eigler <fche@redhat.com>
* compile.c: Don't include "wait.h".
(sim_resume): Use local SIM_WIFEXITED and SIM_WIFSIGNALED macros
instead of WIF* from host.
Add file sim-hload.c - generic load for hardware only simulators.
Review each simulators sim_open, sim_load, sim_create_inferior so that
they more closely match required behavour.
