__OPTIMISE_TIME – If -Otime in use.
__prettyfunc__ name The unmangled name of the current function.
__sizeof_int 4 For sizeof(int) , but available in preprocessor
expressions.
__sizeof_long 4 For sizeof(long) , but available in preprocessor
expressions.
__sizeof_ptr 4 For sizeof(void *) , but available in preprocessor
expressions.
__SOFTFP__ – If compiling to use the software floating-point library.
Set if using -fpu softfpa or -fpu softvfp for ARM or
Thumb, or if using
-fpu softvfp+vfp for Thumb.
__STDC__ – In all compiler modes.
__STDC_VERSION__ – Standard version information.
__STRICT_ANSI__ –Set by -strict .
__TARGET_ARCH_xx – xx represents the target architecture and its value
depends on the target architecture. For example, if the
compiler options
-cpu 4T or -cpu ARM7TDMI are
specified then __TARGET_ARCH_4T is defined, and no
other symbol starting with
_TARGET_ARCH_ is defined.
__TARGET_CPU_xx – xx represents the target cpu. The value of xx is derived
from the
-cpu compiler option, or the default if none
is specified. For example, if the compiler option -cpu
ARM7TM
is specified then _TARGET_CPU_ARM7TM is defined
and no other symbol starting with
_TARGET_CPU_ is
defined.
If the target architecture is specified, then
_TARGET_CPU_generic is defined.
If the processor name contains hyphen (-) characters,
these are mapped to an underscore (
_ ). For example,
-cpu SA-110 is mapped to __TARGET_CPU_SA_110 .
__TARGET_FEATURE_DOUBLEWORD – If the target architecture supports the PLD , LDRD , STRD ,
MCRR , and MRRC instructions.
__TARGET_FEATURE_DSPMUL – If the DSP-enhanced multiplier is available.
