Thu Sep 28 10:13:22 PDT 2000 malcolm * The -ansiC backend had a huge plateau space-leak. By splitting code-generation into two passes (labels then code), we greatly reduce the leak, but introduce a shorter spike later. Change the representation of the code from composed 'shows' to concat'ed strings, and the spike is halved (but still spiky). Overall, much better space usage (although it is still not as good as it could be). Time usage appears to be exactly the same as before (although still not as good as with the -noansiC backend).

patch applied (hat): Small changes towards getting traced-numerics to work. In a Fractional
by Malcolm Wallace 10 Oct '06

10 Oct '06

Tue Aug 22 02:52:05 PDT 2000 malcolm * Small changes towards getting traced-numerics to work. In a Fractional context where the type is unknown, we can't resolve a literal to either Float or Double at compile-time, so we have to generate `fromRational l' where the literal l is a constructed Rational. Unfortunately, traced Rationals have a pretty complex structure, so we have to augment the auxiliary `conRational' with extra arguments in order to build the traced literal Rational correctly. It still doesn't work though. :-( M ./src/compiler98/Case.hs -3 +2 M ./src/compiler98/DbgId.hs +1 M ./src/compiler98/FixSyntax.hs -23 +43 M ./src/compiler98/STGState.hs -1 +4
