VFP predefined preprocessor defines

Hi,

I have to differ in my C code if it is build as Cortex M3 or Cortex M4 with FPU.

With other GCC compiler I use:

#if (defined (__VFP_FP__) && !defined (__SOFTFP__))
#endif

which works perfectly.

Unfortunately this does not work with Rowley Crosssworks, __VFP_FP__ and __SOFTFP__ are always defined, regardless of the compiler settings.

The documentation tells the following:

ARM FPU Type
arm_fpu_type – Enumeration
Specifies the FPU type to generate code for. The
options are:
•  VFP - ARM9/ARM11 based processors
•  VFP9 - the same as VFP
•  VFPv3-D32 - Cortex-A/Cortex-R based processors
•  VFPv3-D16 - Cortex-A/Cortex-R based processors
•  FPv4-SP-D16 - Cortex-M4 processors
The corresponding preprocessor definitions:
•  __ARM_ARCH_VFP__
•  __ARM_ARCH_VFPv3_D32__
•  __ARM_ARCH_VFPv3_D16__
•  __ARM_ARCH_FPv4_SP_D16__
are defined.

But none of these defines are predefined.

I checked it with:

#if defined(__ARM_ARCH_VFP__)
  #error "1"
#endif
#if defined(__ARM_ARCH_VFPv3_D32__)
  #error "2"
#endif
#if defined(__ARM_ARCH_VFPv3_D16__)
  #error "3"
#endif
#if defined(__ARM_ARCH_FPv4_SP_D16__)
  #error "4"
#endif
#if defined(__VFP_FP__)
  #error "5"
#endif
#if defined(__SOFTFP__)
  #error "6"
#endif

For Cortex M4 with FPU I use in the project properties in code generation options the following settings:

ARM FP ABI Type: SoftFP

ARM FPU Type: FPv4-SP-D16

I am using latest version of Rowley Crossworks V2.3.2.2013053101.18474

Any help is appreciated.

Thanks,

Til
