Still playing with Native Boost assembler.
This code instantly crashes Pharo 1.4 with NB installed:
TestAssem swapDoubFirst: 1.0 withSecond: 2.0.
TestAssem>>swapDoubFirst: r1 withSecond: r2
<primitive: #primitiveNativeCall module: #NativeBoostPlugin>
^ NBFFICallout cdecl: #( double ( double r1, double r2 ))
emitCall: [:gen | | asm proxy smpfr scnt|
asm := gen asm.
proxy := gen proxy.
asm pop: asm ECX.
asm fld: asm ESP ptr64 .
asm fld: asm ESP ptr64 + 8 .
asm fxch: asm ST0.
