This patch adds sys$abort() which immediately crashes the process with
SIGABRT. This makes assertion backtraces a lot nicer by removing all
the gunk that otherwise happens between __assertion_failed() and
actually crashing from the SIGABRT.
Instead of pushing the message, file name, line# and function name
separately, we now mash the message, file name and line# into a string
constant and pass that.
This means that the failure path only has to push a single address onto
the stack, reducing the code size and causing the compiler to inline
many more functions containing an assertions (e.g RefPtr::operator*())
Obviously if you wanted minimal size, you could turn assertions off
entirely, but I really like running with assertions, so let's make
a little effort to reduce their impact. :^)
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
