verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective

+/* This is a first cut at checking that debug information matches
+   run-time.  The idea is to annotate programs with GUALCHK* macros
+   that guide the tests.
+
+   In the current implementation, all of the macros expand to function
+   calls.  On the one hand, this interferes with optimizations; on the
+   other hand, it establishes an optimization barrier and a clear
+   inspection point, where previous operations (as in the abstract
+   machine) should have been completed and have their effects visible,
+   and future operations shouldn't have started yet.
+
+   In the current implementation of guality_check(), we fork a child
+   process that runs gdb, attaches to the parent process (the one that
+   called guality_check), moves up one stack frame (to the caller of
+   guality_check) and then examines the given expression.
+
+   If it matches the expected value, we have a PASS.  If it differs,
+   we have a FAILure.  If it is missing, we'll have a FAIL or an
+   UNRESOLVED depending on whether the variable or expression might be
+   unavailable at that point, as indicated by the third argument.
+
+   We envision a future alternate implementation with two compilation
+   and execution cycles, say one that runs the program and uses the
+   macros to log expressions and expected values, another in which the
+   macros expand to nothing and the logs are used to guide a debug
+   session that tests the values.  How to identify the inspection
+   points in the second case is yet to be determined.  It is
+   recommended that GUALCHK* macros be by themselves in source lines,
+   so that __FILE__ and __LINE__ will be usable to identify them.
