I also doubt it has anything to do with the paths. What I did was this: - file to change: $MYPATH/gcc-3.2.3/gcc/gcc.c - path in the patch file: gcc/gcc/gcc.c So I did `cd $MYPATH/gcc-3.2.3' and then `patch -p1 < ../gcc.c.patch'. That should have done the trick, shouldn't it? Yours, Markus ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!

I have discovered code generation problem on AMD64. The patch below corrects code generation. It causes spurious warnings in some other tests (fjf1014.pas, fjf1021h.pas, fjf1021i.pas, fjf768c.pas, fjf768e.pas, fjf768f.pas) but those will require separate fix. In principle other platforms may be affected -- in particular the problem on Mac OSX looks related. diff -u p.orig/expressions.c p/expressions.c --- p.orig/expressions.c 2005-02-16 04:38:36.000000000 +0100 +++ p/expressions.c 2005-02-19 05:17:58.200156608 +0100 @@ -259,20 +259,23 @@ { tree cond, t; int side_effects = TREE_SIDE_EFFECTS (expr); - expr = save_expr (expr); - if (TREE_CODE (expr) == SAVE_EXPR) - TREE_SIDE_EFFECTS (expr) = side_effects; - cond = chklo ? build_implicit_pascal_binary_op (LT_EXPR, expr, min) : NULL_TREE; + tree tmpvar = make_new_variable("range_check", TREE_TYPE (expr)); + tree tv; + cond = chklo ? build_implicit_pascal_binary_op (LT_EXPR, tmpvar, min) : NULL_TREE; if (chkhi) { - tree cond2 = build_implicit_pascal_binary_op (GT_EXPR, expr, max); + tree cond2 = build_implicit_pascal_binary_op (GT_EXPR, tmpvar, max); cond = cond ? build_pascal_binary_op (TRUTH_ORIF_EXPR, cond, cond2) : cond2; } - t = save_expr (build (COND_EXPR, TREE_TYPE (expr), cond, build (COMPOUND_EXPR, - TREE_TYPE (expr), build_predef_call (co->range_checking > 1 ? p_IORangeCheckError : p_RangeCheckError, - NULL_TREE), expr), expr)); - if (TREE_CODE (t) == SAVE_EXPR) - TREE_SIDE_EFFECTS (t) = side_effects; + t = build (COMPOUND_EXPR, TREE_TYPE (expr), + build_predef_call (co->range_checking > 1 ? p_IORangeCheckError : p_RangeCheckError, + NULL_TREE), tmpvar); + t = build (COND_EXPR, TREE_TYPE (expr), cond, t, tmpvar); + tv = build (MODIFY_EXPR, TREE_TYPE (expr), tmpvar, expr); + PASCAL_VALUE_ASSIGNED (tmpvar) = 1; + TREE_SIDE_EFFECTS (tv) = 1; + t = build (COMPOUND_EXPR, TREE_TYPE (expr), tv, t); + TREE_SIDE_EFFECTS (t) = side_effects; return t; } } -- Waldek Hebisch hebisch(a)math.uni.wroc.pl

Apple's marketing department acts as if it invented the "gcc" compiler, the "as" assembler and the "ld" linker as part of XCode, but that is far from the truth. Apple's gcc compiler and as assembler are hacked versions of software of the Free Software Foundation (<http://www.gnu.org/>).

Update for Mac OS X
by Adriaan van Os 18 Feb '05

18 Feb '05

The gpc compiler for Mac OS X, available from <http://www.microbizz.nl/gpc.html>, has been updated. The distribution is based on gcc-3.4.3, gpc-20041218 and Waldek's patches. The downloads include separate packages for: • an installer for the compiler's binaries (for Mac OS X 10.3 and later) • sources, patches and building instructions (for Mac OS X 10.2 and later) • an updated Mac OS X assembler, linker and utilities (cctools-528.5) • updated Mac OS X Pascal Interfaces (version 1.0.7) Regards, Adriaan van Os
