2003-09-21 Jonathan Larmour <jifl@eCosCentric.com>
* cdl/hal_sh.cdl: CYGHWR_HAL_SH_FPU_REGS is only needed if there's an
FPU.
* include/hal_var_bank.h (HAL_THREAD_INIT_CONTEXT_FPU): Use FPSCR
init value from HAL register definitions.
2003-09-19 John Dallaway <jld@ecoscentric.com>
* cdl/hal_sh.cdl: Specify default CDL values for sh4_202_md target.
2003-09-11 Nick Garnett <nickg@ecoscentric.com>
* include/hal_var_bank.h (HAL_THREAD_INIT_CONTEXT_FPU): Changed
initial value of fpscr to do round-to-nearest rather than
round-to-zero.
2003-09-08 Nick Garnett <nickg@ecoscentric.com>
* src/vectors.S (cyg_hal_default_exception_vsr): Added code to
switch to interrupt stack when fielding exceptions from RedBoot or
some other ROM monitor. Without this we get potential stack
overflows when debugging via the network.
2003-09-05 Nick Garnett <nickg@ecoscentric.com>
* include/hal_arch.h:
* include/hal_var_bank.h:
* include/hal_var_bank.inc:
* src/context.S:
Added support for floating point state save and restore and GDB
* src/hal_misc.c (hal_delay_us): Fixed implementation of this
routine so that it actually works.
* src/hal_syscall.c:
Added support for all supportable syscalls.
* src/sh_stub.c:
Added check in __is_bsp_syscall() for trap 34 traps using the TRA
register.
* src/vectors.S: Set startup stack size to the same as the
interrupt stack size. In some configurations of RedBoot the
previous value was too small.
* include/sh_stub.h:
Fixed HAL_STUB_PLATFORM_STUBS_FIXUP() to only rewind for a
breakpoint. Traps are not rewound.
* cdl/hal_sh.cdl: Added option for SH architecture FP register
count.
