- Subject: [ECOS] get arm7 registers
Hi,
I want to get the general registers (r0 to r15 in supervisor mode) at anytime.
With the synthetic target I do it with
#define __get_thread_context(__context__){\
asm( "mov %%edi,%0 \n\t"\
"mov %%esi,%1 \n\t"\
"mov %%ebp,%2 \n\t"\
"mov %%esp,%3 \n\t"\
"mov %%ebx,%4 \n\t"\
: "=m" (__context__[S_REG_EDI]),"=m" (__context__[S_REG_ESI]),\
"=m" (__context__[S_REG_EBP]),"=m" (__context__[S_REG_ESP]),\
"=m" (__context__[S_REG_EBX]));\
}
because there was not a lot of registers to save. I would know if anybody have an
idea to get those with a more proper method (like get all registers and store it, with
a specific arm instructions, in memory - in fact in a HAL_SavedRegisters structure).
Thanks a lot for your future help and answers.
Best regards jjp.
