bfloat16_t
was added to softfloat's softfloat_types.h
by this PR.
https://github.com/ucb-bar/berkeley-softfloat-3/blob/080c31c72d5c3fd813584ea990e8a3aa10e902eb/source/include/softfloat_types.h#L51
So it should be present on a recent version of softfloat
. Some issues certainly remain (I know at least one patch is being prepared to fix some warnings and some other format tests broken when BFLOAT16 is enabled).
Could you provide more details ? (which target are you building on / for, what are the actual errors you get ?)

Same issue faced. Here is the error details.

i created a fork of testfloat to compile individual PE files. i can then run these exe's before and after transforming them via binary rewriting/obfuscation techniques to ensure we did not break any semantics of the code.
https://github.com/backengineering/testfloat-pe
I then included pre-compiled versions of these binaries into our larger set of test files which our CI pipeline uses everytime we change our obfuscation passes.

I think i either didnt compile the bfloat related tests or i just commented them out.... Just creating this issue so it can be solved on your end of things, i can do without tests which use bfloat all together...
