In "com.ibm.wala.cast.test", the "cbuild.sh" script is gone entirely.
Instead, "pom.xml" directs Maven to run "make" directly. We still
have a "Makefile.configuration" file in this project, but this file is
now independent of where WALA is being built and of where Java is
installed.
In "com.ibm.wala.cast", a small "cbuild.sh" remains, to do some
special processing involving Visual Studio variables under Windows.
When not building under Windows, "cbuild.sh" now simply runs "make".
It may well be possible to hoist the special Windows stuff up into
this subproject's "pom.xml", or to change that "pom.xml" to run
"cbuild.sh" only when on Windows, and to run "make" directly
otherwise. I don't know "pom.xml" stuff very well, though. We still
have a "Makefile.configuration" file in this project, but this file is
now independent of where WALA is being built and of where Java is
installed.
The changes I've made in both "Makefile.configuration" files use GNU
make extensions. I assume that's safe because "Makefile.definitions"
already relies on GNU make.
Along the way, I also converted many "for (;;)" loops into modern
"for (:)" loops. I didn't systematically look for all opportunities
to do this, though. I merely made this change where I was already
converting raw Iterator uses into modern Iterator<...> uses.
Better use of generics also allowed many casts to become statically
redundant. I have removed all such redundant casts.
Only three raw-types warnings remain after this batch of fixes. All
three involve raw uses of CallGraphBuilder. I've tried to fix these
too, but it quickly snowballs into a cascade of changes that may or
may not eventually reach a statically-type-save fixed point. I may
give these last few problem areas another go in the future. For now,
though, the hundreds of other fixes seem worth keeping even if there
are a few stragglers.
This commit may change some public APIs, but only by making weaker
type signatures stronger by replacing raw types with generic types.
For example, we may change something like "Set" into "Set<String>",
but we're not adding new arguments, changing any
underlying (post-generics-erasure) types, etc.
