Brian Anderson 0f0fa26c72 Enforce variance rules for mutable types 2011-10-17 20:51:34 -07:00
Brian Anderson 48d351b21e Add a variance transform for calculation of recursive variance 2011-10-17 19:37:34 -07:00
Brian Anderson d6613384fd Introduce covariance, contravariance and invariance to the type unifier 
This will be used to resolve some problems with mutable? covariance and also
to implement function subtyping
 2011-10-17 19:34:12 -07:00
Brian Anderson b61578e1cd Don't unify from mutable? to immutable 
Immutable is supposed to be a subtype of mutable-huh.
 2011-10-17 16:36:49 -07:00
Brian Anderson f7a825c614 Split record_var_binding into methods for expected and actual 
This allows unify to maintain the same subtype relationship between
expected and actual throughout unify, which we are going to need
for mutable? and for function types.
 2011-10-17 16:36:49 -07:00
Brian Anderson 1a64153b24 Correct two more analyses of mutable? as mutable 
I can't come up with test cases but this seems correct.

Brian Anderson 4d9d889dbf Don't allow assignment to mutable-wha? 2011-10-17 16:35:33 -07:00

Brian Anderson 007422cc04 Change the linkage order on linux and add -ldl 
-lrt and -ldl need to be specified after -lrustrt since they are only used by
rustrt.

Brian Anderson b42e551285 Only link librt on linux 2011-10-16 02:36:42 -07:00
Haitao Li ad5014bf4c Fix link error by explicitly link needed DSOs 
Building Rust(version 280bc56) on Ubuntu 11.10 failed with link error,
like:

compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/lib/libstd.so
compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/bin/rustc
/local/src/rust/build/stage0/lib/rustc/i686-unknown-linux-gnu/lib/librustrt.so:
undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
error: linking with gcc failed with code 1

GCC toolchain released by Ubuntu 11.10 introduced a few compiler flags
that are different with upstream GCC[1]. Flags "-Wl,--as-needed' and
'-Wl,--no-copy-dt-needed-entries' are passed by default.

Function clock_gettime from librt is used by librustrt, indirectly by
rustc. It is necessary to explicitly pass the "-lrt" flags when building
rustc.

Please note since the toolchain changes will be the default in the next
release(2.22) of binutils, this is not actually a Debian/Ubuntu specific
issue.

Marijn Haverbeke 0a01144797 Use trans_expr_save_in instead of trans_expr when appropriate 
This guards against passing a save_in destination to nil or bot-typed things.

Marijn Haverbeke 06257d66e7 Don't crash when reporting an unresolved import in the nil scope 
Closes #1027

Brian Anderson 3808a498cd Remove an unnecessary visitor from rustc::middle::fn_usage 2011-10-13 14:55:50 -07:00
Brian Anderson acf9b83e71 Fix a use of visit in rustc::middle::fn_usage 
This was working by just skipping an AST node instead of doing the advertised
check. I can't find a test case for it, but this is more correct.

Brian Anderson bc4c3df1bf Don't allow the value of generic bare functions to be taken 
Issue #1038

Brian Anderson 89466ffd74 Rename rustc::middle::unsafeck to fn_usage 
I'm going to add further checks unrelated to unsafe.

Marijn Haverbeke 6a7800508b Make trans_anon_obj properly thread its bcx 
Closes #893

Unfortunately, anon objs are still so broken as to be useless
(fields don't work).

Marijn Haverbeke e4c91fdf65 Properly fill single-variant zero-arg tag values. 
Closes #1034. Closes #1035.
