Software News   Software News : vbcc 0.8i available
   posted by MikeB on 9-Aug-2005 8:12:54 (2383 reads)
A new version of the ISO C compiler vbcc is now available. (Already included in the latest OS4 SDK)

"New: PowerPC code generator: -baserel32os4 option enables an OS4-specific base-relative addressing mode, using 32-bit offsets to base register r2 (pointing to the beginning of the .data section)."

Look here for the complete list of changes.

Great news!

Here there are benchmarks:
http://sun.hasenbraten.de/vbcc/index.php?view=benchmarks
But they are very old (gcc 2.95.3) anyone knows the situation now with gcc3 or better gcc4?
Pretty impressive is the difference in the executable size 2.6Mb vs 870Kb in flavour of vbcc.

Thanks bye

Richi

I sent the benchmarks for GCC 3.4.3 (OS4) to Frank but he hasn't published them yet.
Maybe because he lacks time, maybe because it shows VBCC isn't faster than GCC in every test.
But it's still a very good compiler, every version gets better.

@AV, agreed. Especially when compiling on a very slow system, like a classic Amiga, VBCC beats the heck out of GCC in compiling speed ;)

All in all, it's a nice C compiler.

@Anyone

This is the same version as in the OS4 SDK released 2 days ago.

@Franck

What about adding version numbers in your binaries?

Well, you are probably not interested in the version of each of those binaries but in the version number of the whole package. That's in the vbcc folder (vbcc_version) and vbcc itself prints the version in "very verbose" mode.

Why not?

version "filename" is such a nice feature.

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

I have a dumb question

What is the baserel option used for? IIRC, in 68K code base relative was used because the old Amiga chunk format didn't have a global offset table like ELF does, so you need the code to be different for position-independent code vs 'regular' code. Does OS4 not use the GOT in ELF binaries (so you need this feature to write .libraries), or is it something else?
