HI Mike,
2011/11/11 Mike Frysinger vapier@gentoo.org:
so the ISA version only affects the generated libraries right ? i can still use any of the compilers to output any ISA version ?
i grabbed the v1f and it seems to build the one nds32 board in the tree fine.
i ripped it down to the min needed for u-boot, so people can grab the 4.3MiB: http://dev.gentoo.org/~vapier/u-boot/nds32.tar.xz -mike
Unfortunately, wrong.
ISA will affect the assembly and binary patterns, also some basic stack operation. You cannot run v1 v1f binary on the adp-ag101 board. You also cannot run v1f on the chip which didn't have floating point unit. So, you cannot run v1f binary on adp-ag101p board. There will decode floating related ISA as non-floating point then lead fault.
The capability is listed as follows. adp-ag101: v0 binary only. adp-ag101p: v0 and v1 binary. adp-ag102: v0, v1, v1f
