Hi Oliver,
+#define FIXED_R18 0
{ \
0, 0, 0, 0, 0, 0, 0, 0, /* R0 - R7 */ \
0, 0, 0, 0, 0, 0, 0, 0, /* R8 - R15 */ \
- 0, 0, 0, 0, 0, 0, 0, 0, /* R16 - R23 */ \
+ 0, 0, FIXED_R18, 0, 0, 0, 0, 0, /* R16 - R23 */ \
This is equivalent to having a zero in the table given the #define is
unconditional.
It's best to use the existing mechanisms to change registers, this should be
done
in aarch64_conditional_register_usage given very similar changes for floating
point and SVE are already there.
Cheers,
Wilco
