Obviously, it will be necessary to package the VFP versions of the
runtime libraries. The shared libraries should be stored in
!SharedLibs.lib.abi-2/0.vfp. Binaries needs to be linked with
-mfpu=vfp so that the dynamic linker knows to look for VFP libraries.
I can't remember if I documented that; I'll have to check.
So, what do I need to do a release:
svn co ...
cd gcc4
<bump version number in riscpkg-versions, setup-gcc-params>
./build-world
./create-gcckit -pkg
./create-riscpkg
As Chris says, you'll have to do make ronative after build-world.
Anything else? I don't need to do anything to the compiler build to enable
VFP? It's purely a runtime flag for GCC?
That's right, the VFP libraries are built by default. By specifying
-mfpu=vfp to compiler and linker, GCC will generate VFP instructions,
and select the correct runtime libraries.
Lee or Chris, would you mind adding the VFP libraries to create-riscpkg,
since you know what's necessary and I dont?
Yes, I should be able to do that; shall I assume that for simplicity,
the VFP libraries are to be bundled with the normal ones?
Lee.
