880fd788eb rustc: Add an extra flag to object tydescs so that shapes know how to find the captured subtydescs 2011-08-25 12:01:10 -07:00

c6155d1fd1 Change "pred" to "pure fn" (but still accept "pred") 
This is part 1 of changing the "pred" keyword to "pure fn".
Right now, the compiler accepts both "pred" and "pure fn".

629ee94a0b Back out copy-glue

15b540ded4 Use a single builder object throughout 
This seems to be faster than creating separate ones for each block
context.

b9112525ba Move to a more lightweight builder system 
You now do

    bld::Ret(bcx, someval)

where you used to say

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

e58c48bdda Optimize += [x] into a simple push operation 
This is a preparation for making vectors always-on-the-heap again,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

Reduces compiler code size by 3%

7d08678b74 Implement pattern guards 
The syntax is

    alt x {
        mypat where mycond { ... }
    }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

b24f978011 Drop arguments on the caller side, not the callee 
This makes it easier for the caller to optimize the take/drop away for
temporary values, and opens up new possibilities for alias handling.

Breaks tail calls.

Marijn Haverbeke
35c962e9a1 Pass structural types by pointer, not by value 
If we lose tail calls, this is possible. It simplifies things a lot.

Direct motivation: We want ivecs with pointers pointing into
themselves. When copying those, the pointers have to be adjusted. It
is impossible to this when copying them with Load/Store.

0a8bffceb3 Simplify the _rust_main/rust_start interface 
rust_start will always call _rust_main with the command line args, and it is
_rust_main's responsibility to free the args ivec heap. _rust_main will be
generated slightly differently depending on whether main takes an ivec or not:
if so then it's just passed through to main, otherwise it frees the ivec
directly.
