Hi
I am trying to build fpc and Lazarus for ARMHF for a pcDuino. The processor is
an AllWinner A10. I used fpc 2.6.2 to build fpc 2.7.1 from source. When I
compile a test program with the following parameters
fpc -dFPC_ARMHF -Caeabihf -Cparmv6 -Cfvfpv3_d16 test.pas
I get the following output from readelf -a (just showing last bit)
Attribute Section: aeabi
File Attributes
Tag_CPU_name: 6
Tag_CPU_arch: v6
Tag_ARM_ISA_use: Yes
Tag_THUMB_ISA_use: Thumb-1
Tag_FP_arch: VFPv3-D16
Tag_DIV_use: Not allowed
The output of readelf -a /bin/ls is as follows:
Attribute Section: aeabi
File Attributes
Tag_CPU_name: 7-A
Tag_CPU_arch: v7
Tag_CPU_arch_profile: Application
Tag_ARM_ISA_use: Yes
Tag_THUMB_ISA_use: Thumb-2
Tag_FP_arch: VFPv3-D16
Tag_ABI_PCS_wchar_t: 4
Tag_ABI_FP_denormal: Needed
Tag_ABI_FP_exceptions: Needed
Tag_ABI_FP_number_model: IEEE 754
Tag_ABI_align_needed: 8-byte
Tag_ABI_align_preserved: 8-byte, except leaf SP
Tag_ABI_enum_size: int
Tag_ABI_HardFP_use: SP and DP
Tag_ABI_VFP_args: VFP registers
Tag_CPU_unaligned_access: v6
Tag_DIV_use: Not allowed
It seems that fpc in fact does not produce ARMHF executables with the
parameters that I use. Am I using the wrong parameters or is something broken
in the ARMHF support ?
