 #if 0 at the obvious places in liboil/arm/*vfp*[cS] makes it compile;
 I'll tell you in a couple of days when the compilation has finished
 whether gnash works with that.

 A certain gentleman told me privately that using the generic coprocessor
 opcodes instead would have worked, but this requires lots of ARM ARM
 reading and editing, and - hopefully - the library won't try to actually
 use the vfp routines on my Shark.

 The assembler file holds some instructions with very specific
 compiler flags to use; so probably the package just needs some work
 on the Makefile.* in there to make it use the right flags.

State-Changed-By: maya@NetBSD.org
State-Changed-When: Mon, 17 Sep 2018 12:42:21 +0000
State-Changed-Why:
This package will never use vfp instructions on netbsd/arm, because it relies on /proc/cpuinfo to check for vfp availability and netbsd/arm doesn't provide this info there AFAIK. It would be good to make the package compile the vfp code whenever it thinks it's possible, as it only enables it when passing a runtime check. It looks like upstream has implemented this change - the code is all depending on
#if defined(__VFP_FP__) && !defined(__SOFTFP__)
I am closing this bug rather than putting in feedback because it's a very old bug report that is likely fixed. If you are still having issues, feel free to make a new bug report.
