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.
