time ago! Notice there was in past in the math.h inline asm 68881
instruction that generate 68881 instruction even with 68020-60 option
but now this is corrected for a long time.
As I see it, maybe netbsd guys decided to implement their libm in this
way but I may be wrong. For me it's a little bit difficult to separate
this stuff since when we're talking about sin/cos (060 emulated stuff)
it's clear math lib will be used. So question is -- where gcc even
have a _chance_ to use these emulated instructions?
I never see any problem for tiny_gl and mesa_gl but you have perhaps true, in fact the option -m68020-60 is not the only flag that tell to compiler how generate binary, there is options when gcc is compiled I think it's define in CPP_SPEC and (I can't remember the file but sure some peoples can answer) there is a file to define the SPEC for compiler, it is possible I have modify it for not add 68881 instructions or it was already ok. I'm wrong?
