mov eax, st(0) - :)

[marzecTM]

greets,

tried to do a simple little prog, fb goes crazy and outputs this

D:\projects\pointinpoly>fbc -r pipcoll.bas
pipcoll.asm: Assembler messages:
pipcoll.asm:56: Error: suffix or operands invalid for `mov'
pipcoll.asm:69: Error: suffix or operands invalid for `mov'

seems like reg allocation is farked up cause the thing tries mov eax, st(0). i used the 0.13 cvs version so i guess this has already been fixed right?

EDIT: just tried it with official 0.12 beta same result. problem is in matrixIdentity.

here's the source

Code:

option explicit

type Vertex2D
    x as single
    y as single
end type

type Matrix
    m( 0 to 2, 0 to 2 ) as single
end type

sub matrixIdentity ( mat as Matrix )

dim row as integer
dim col as integer

    for row = 0 to 2
        for col = 0 to 2
            if( row = col ) then
                mat.m( row, col ) = 1.0
            else
                mat.m( row, col ) = 0.0
            end if
        next col
    next row
    
end sub

sub matrixTranslation ( mat as Matrix, x as single, y as single )
  
   matrixIdentity ( mat )
   mat.m( 0, 2 ) = x
   mat.m( 1, 2 ) = y
  
end sub

sub matrixMultiVert2d ( mat as Matrix, vec as Vertex2D, outvec as Vertex2D )

    outvec.x = vec.x * mat.m( 0, 0 ) + vec.y * mat.m( 0, 1 ) + mat.m( 0, 2 )
    outvec.y = vec.x * mat.m( 1, 0 ) + vec.y * mat.m( 1, 1 ) + mat.m( 1, 2 )

end sub



screen 13


dim mat as Matrix
dim vec as Vertex2D
dim outvec as Vertex2D

matrixTranslation ( mat, 160, 100 )
vec.x = 0: vec.y = 0

matrixMultiVert2d( mat, vec, outvec )

pset( outvec.x, outvec.y ) , 4

have fun

It's within these two commands:

Code:

if( row = col ) then
            mat.m( row, col ) = 1.0
         else
            mat.m( row, col ) = 0.0
         end if

if you comment out the mat.m()= lines then it will compile.

Maybe its not being passed to the sub properly?

Fixed, i hate byref args, no wonder no other language got those (okay, PASCAL has them too, screw it).

Problem was at parser3 (1 single line), it will take a while to SF update the CVS tho.. problem would only happen with field arrays of different classes than integer, on UDT args passed by reference.

eeks strange that never happened before...
