Compiler Speed Trials

[boriel]

Hi, I've rerun your BM7 and BM8 tests against 1.2.8-s682 with -O3 and BM7 gives 1.05 segs, whilst BM8 outputs 19.05 (the best ever).

These are the code benchmarks I used:

Code:

''' BM7 Benchmark by britlion.
''' Compiles on: ZX Basic, Hisoft, Sinclair BASIC
''' Expected running time: 2.1 segs (ZX BASIC)

7 REM :INT +a,k,v,i,m()
  DIM a, k, v, i as UInteger

8 REM : OPEN#
9 CLS
10 POKE 23672,0: POKE 23673,0
90 POKE 23672,0
100 LET a=0: LET k=5: LET v=0
110 LET a=a+1
120 LET v=k/2*3+4-5
130 GO SUB 1000
140 DIM m(5) as UInteger
150 FOR i=1 TO 5
160 LET m(i)=a
170 NEXT i
200 IF a<1000 THEN GO TO 110: END IF
210 PRINT CAST(FIXED, PEEK(Uinteger, 23672))/50.0
999 STOP
1000 RETURN
1001 PRINT v, m(0)

Code:

REM BM8
POKE Uinteger 23672, 0

DIM i,j as ubyte
j=2
FOR i=1 to 100
result=j^2
result=ln(j)
result=sin(j)
next i

t = Peek(Uinteger, 23672)
print CAST(Float, t) / 50
PRINT result : REM use result to avoid it being optimized

Can you check it? Maybe you're using a different benchmark??
