[fpc-devel] freepascal on armhf again

[peter green]

I decided to take another look at the freepascal armhf issue and decided 
that the first step would be to build freepascal with vfp enabled but 
still the softfloat ABI then once that was working.

(note: i'm currently working on upstream fpc svn, if/when I get things 
working reasonablly on armhf I will look into backporting to the version 
in debian)

Unfortunately when I try to build freepascal with vfp enabled

make all 'OPT=-dFPC_ARMEL -CfVFPV3'

I get assembler errors.

Any idea what exactly these errors mean (e.g. do any processors support 
these instructions and if so which ones), what is causing this (e.g. why 
is freepascal generating these instructions) and what if anything I can 
do about it?
