BTW: here's a Object-Pascal compiler based on LLVM project: http://code.google.com/p/llvm-pascal/ (I think that there are more than one of these)
For info in LLVM: http://llvm.org/ IBM has reportedly become more interested in LLVM for z: http://www.phoronix.com/scan.php?page=news_item&px=MTM1MTc and has contributed some patches to the LLVM project (at least for C/C++ compilers): http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-April/061170.html .. enough links; starting to look like a garlic.com list :-) Kirk Wolf Dovetailed Technologies http://dovetail.com On Tue, Oct 1, 2013 at 8:40 PM, Tony Harminc <t...@harminc.net> wrote: > On 1 October 2013 20:06, Bernd Oppolzer <bernd.oppol...@t-online.de> > wrote: > > Stanford PASCAL also generates P-Code in the first step, > > which in the second step is translated to 370 machine code. > > Interesting; I had thought that P-code was only interpreted. > > > BTW: The P-Code of the 1982 variant of the Stanford compiler > > had been extended compared to the 1979 variant, and because > > I found only a description of the 1979 variant, it was a little bit > > complicated to find out what the "new" P-Code instructions do. > > There is not "one" P-Code, but many variants of P-Code. > > > > And: it turned out, that the P-Code is not so machine-independant > > as it should be.
