9a269a3aa8 Allow binding of nested patterns 
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is

    boundvar@subpattern

Which will match the subpattern as usual, but also bind boundvar to the
whole matched value.

9a738fd61d rt: Various tweaks to make __morestack unwinding work on linux 
When unwinding through __morestack the stack limit in the TLS is invalidated
and must be reset. Instead of actually landing at __morestack we're
just going to make all our Rust landing pads call upcall_reset_stack_limit,
which will find the stack segment that corresponds to the current stack
pointer and put the limit in the TLS.

Also massively expand the stack segment red zone to make more room for the
dynamic linker. Will fix in the future.

47ea57fead rustc: Add suffix ".rc" to LLVM module identifier 
LLVM code generator emits the ".file filename" directive for ELF
backends. Value of the "filename" is set as the LLVM module identifier.
Due to a LLVM MC bug[1], LLVM crashes if the module identifer is same as
other symbols such as a function name in the module.

This patch adds a ".rc" suffix (means crates) to LLVM module identifier
to workaround the bug.

Fixes issue #1251.

f6491bb426 Update stdlib, compiler, and tests to new kind system 
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

cefff237bf Make tag, resource and object constructors take their arguments by copy 
Doing something like some([1, 2, 3]) will now no longer create a temporary
copy of the vector. It will also be easier for the kind checker to see that
putting a resource into a data-structure constructor is safe.

4e03112141 Add a pass-by-copy parameter passing convention 
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.

9ff6f816ba Fix handling of loops and conditionals in alias.rs 
It now threads information about invalidated aliases through the AST
properly. This makes it more permissive for conditionals (invalidating
an alias in one branch doesn't prevent you from using it in another),
and less permissive for loops (it now properly notices when a loop
invalidates an alias that it might still use in another iteration).

61b604580b Fix alignment of interior pointers of dynamic-size types. Closes #1112 
GEP_tup_like finds interior pointers by creating a tuple of all the types
preceding the element it wants a pointer to, then asks for the size of that
tuple. This results in incorrect pointers when the alignment of that tuple
is not the alignment of the interior type you're getting a pointer to.

7dacccde94 Make shared kind the default only for generic functions 
You almost never want a function with pinned type params. For
types, objects, resources, and tags, pinned types are actually often
more sane. For most of these, shared rarely makes sense. Only tricky
case is objs -- you'll have to think about the kinds you want there.

7114702496 Change the way block calls are parsed, mark them as block-calls. 
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.

cb4e99b688 Don't allow vectors of pinned kinds 
Vectors of pinned kinds can't be safe because most interesting uses of vector
perform copies

dbf472b0df rustc: Switch to cdecl for all calls. This is needed to make stack growth efficient, as I need to use eax and ecx in the function prologue and can't afford to stomp on incoming arguments. 2011-09-28 10:22:02 -07:00

759fc101fb Get rid of might_not_init kludge in init_local. 
Initializing something is now safe wrt to cleanups (so the cleanup for the
local is only registered after the initialization.)

16d5aaa962 Wait with registering cleanups for locals until after the init code ran 
Fixes a double-cleanup that was breaking unwind-tup.rs under valgrind.

a96b16e8c3 Make it again possible to initialize resource locals via assignment 
Some special cases allow both 'let a <- my_resource(x)' and
'let a = my_resource(x)' to work as expected despite ostensibly being
copies and moves.
