This allows to be almost as + fast as -dont-load-proofs, while being safer (no creation of axioms) and + avoiding feature restrictions (Print and Print Assumptions work ok). - Experimental support added for camlp4 (the one provided alongside ocaml), simply pass option -usecamlp4 to ./configure. By default camlp5 is used. - Revised build system: no more stages in Makefile thanks to some recursive diff --git a/doc/refman/RefMan-com.tex b/doc/refman/RefMan-com.tex index f808047b12..aaa962570b 100644 --- a/doc/refman/RefMan-com.tex +++ b/doc/refman/RefMan-com.tex @@ -265,9 +265,25 @@ The following command-line options are recognized by the commands {\tt \item[{\tt -dont-load-proofs}]\ - This avoids loading in memory the proofs of opaque theorems - resulting in a smaller memory requirement and faster compilation; - warning: this invalidates some features such as the extraction tool. + Warning: this is an unsafe mode. + Instead of loading in memory the proofs of opaque theorems, they are + treated as axioms.
