Dear NXP support,
I tried to compile FreeRTOS in S32 DS with GHS compiler.
As "kregs" is a special VLE constraint and GHS compiler cannot be aware of it. So I changed "=kregs" (ulCriticalNesting) to "=e" (ulCriticalNesting) and enable enable option "-gnu_asm_se_vle_register".
/* Increment critical nesting count */
__asm__ volatile
(
"mfsprg %0, 1 \n\t" // get critical nesting count from SPRG1
"se_addi %0, 1 \n\t" // increment
"mtsprg 1, %0 \n\t" // store to SPRG1
// "=kregs" (ulCriticalNesting)
: "=e" (ulCriticalNesting)
);
}
static portFORCE_INLINE UBaseType_t portDECREMENT_CRITICAL_NESTING( void )
{
UBaseType_t ulCriticalNesting;
/* Decrement critical nesting count */
__asm__ volatile
(
"mfsprg %0, 1 \n\t" // get critical nesting count from SPRG1
"se_subi %0, 1 \n\t" // decrement
"mtsprg 1, %0 \n\t" // store to SPRG1
//: "=kregs" (ulCriticalNesting)
: "=e" (ulCriticalNesting)
);
But then all VLE half-word instructions (the ones that begin with se_) are considered as "syntax error".
How to fix this error? Attached is this project.
All options as below:
