Thank you, it working ;)

I had the same problem I used __asm which worked. I also found a define for
__asm__, but I have not tried it.

Subject: [lpc2000] Crossstudio and asm functions

In Crossstudio 1.7 this functions works correctly:
static inline cpu_t get_cpsr(void)
{
cpu_t val;
asm volatile ("mrs %[val], cpsr\n":[val]"=r"(val):);
return val;
}

static inline void set_cpsr(cpu_t val)
{
asm volatile ("msr cpsr, %[val]\n" ::[val]"r"(val) );
}

In Crossstudio 2.0 I have error:
'asm' undeclared (first use in this function)
when I remove volatile keyword, I have error
asm ("mrs %[val], cpsr\n":[val]"=r"(val):);
^ expected ')' before ':' token
What is wrong in this functons ?

Either switch off the "force ANSI compliance" compiler option, or replace
asm with __asm.
