What are the model and architecture specific, buildin defines in gcc?
Like "_avr_" or "_arm_" on other architectures?

From the gcc/config/xtensa/xtensa.h:
There are no model-specific builtins, you can get them from the overlay files.
Code: Select all
/* Target CPU builtins. */
#define TARGET_CPU_CPP_BUILTINS() \
do { \
builtin_assert ("cpu=xtensa"); \
builtin_assert ("machine=xtensa"); \
builtin_define ("__xtensa__"); \
builtin_define ("__XTENSA__"); \
builtin_define (TARGET_WINDOWED_ABI ? \
"__XTENSA_WINDOWED_ABI__" : "__XTENSA_CALL0_ABI__");\
builtin_define (TARGET_BIG_ENDIAN ? "__XTENSA_EB__" : "__XTENSA_EL__"); \
if (!TARGET_HARD_FLOAT) \
builtin_define ("__XTENSA_SOFT_FLOAT__"); \
} while (0)
