Douglas Gregor f994f062fd PCH support for inline assembly statements. 
This completes support for all of C (+ extensions). We can (again)
build a PCH file for Carbon.h.

 2009-04-16 02:45:14 +00:00
Douglas Gregor 4c5cd33527 PCH support for CompoundLiteralExpr. This is the last C expression 
that does not require PCH support for statements. Only AddrLabelExpr,
StmtExpr, and BlockExpr remain (for C).

Douglas Gregor 8324327993 For source location entries that describe instantiations, encode the 
token length in the PCH file rather than trying (and failing) to
reconstruct it be getting the spelling token's length.

Douglas Gregor 67fdb085b9 PCH support for CStyleCastExpr and BinaryOperator expression kinds. 
llvm-svn: 69119
 2009-04-15 00:25:59 +00:00

llvm-svn: 69106
 2009-04-14 23:59:37 +00:00
Douglas Gregor f0b575f79d Add PCH support for ImplicitCastExprs. This is the first expression 
kind PCH handles that has an expression as an operand, so most of this
work is in the infrastructure to rebuild expression trees from the
serialized representation. We now store expressions in post-order
(e.g., Reverse Polish Notation), so that we can easily rebuild the
appropriate expression tree.

llvm-svn: 69084
 2009-04-14 21:55:33 +00:00
Douglas Gregor feb84b0074 PCH support for a few very, very simple kinds of expressions. Hook up 
expression (de-)serialization for VLAs, variable initializers,
enum constant initializers, and bitfield widths.

llvm-svn: 69075
 2009-04-14 21:18:50 +00:00
Douglas Gregor 1a0d0b9acc When writing a PCH file, keep track of all of the non-static, 
non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

llvm-svn: 69005
 2009-04-14 00:24:19 +00:00
Douglas Gregor a541485bab Partial PCH support for FileScopeAsmDecl and BlockDecl. Both require 
expression or statement serialization before we can test them.

llvm-svn: 69002
 2009-04-13 22:49:25 +00:00
Douglas Gregor 92f056fadf PCH support for functions and their parameters. 
llvm-svn: 68997
 2009-04-13 22:18:37 +00:00
Douglas Gregor 183671e2d2 PCH support for record decls/types and their fields. Now that we can 
handle the definition of __builtin_va_list on x86-64, eliminate the
forced -triple in PCH tests to get better coverage.

llvm-svn: 68988
 2009-04-13 21:20:57 +00:00
Douglas Gregor 1daeb69f95 Add PCH support for enumerations and enumerators. 
llvm-svn: 68974
 2009-04-13 18:14:40 +00:00
Douglas Gregor 4c7626e7b6 Include the SourceManager's line table in the PCH file. We can now 
properly cope with #line directives in PCH files.

llvm-svn: 68963
 2009-04-13 16:31:14 +00:00
Chris Lattner 0af3ba1748 implement the microsoft/gnu "__COUNTER__" macro: rdar://4329310 
llvm-svn: 68933
 2009-04-13 01:29:17 +00:00
Chris Lattner c523d8e88c now that we have an identifier table in the PCH file, finish hooking up 
macro deserialization.  We now correctly install II's in tokens, handle
function-like macros, etc.

llvm-svn: 68882
 2009-04-11 21:15:38 +00:00
Chris Lattner 225dd6c830 add some #includes for better compatibility with gcc 4.4, 
thanks to Tobias Stadler for pointing this out.

llvm-svn: 68868
 2009-04-11 18:40:46 +00:00
Douglas Gregor 3ed42cb0b3 Store unique IDs for identifiers in the PCH file. Use some bitmangling 
so that we only need to perform the lookup and identifier resolution
once per identifier in the PCH file.

llvm-svn: 68846
 2009-04-11 00:14:32 +00:00
Douglas Gregor 92863e475e Compare the predefines buffer in the PCH file with the predefines 
buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).

When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

llvm-svn: 68838
 2009-04-10 23:10:45 +00:00
Chris Lattner 34321bcd0b add support for reading macros. This does all the reading (with a bunch of 
fixme's, e.g. for tokens with identifiers) but does not actually install
them.  Some details with the predefines buffer needs to be sorted out first.

Douglas Gregor bfbde53ce1 Encode the target triple in the PCH file, and check that target triple when using the PCH file 
llvm-svn: 68824
 2009-04-10 21:16:55 +00:00
Douglas Gregor 55abb2389d Implement serialization/deserialization of LangOptions in the PCH 
file. When de-serializing LangOptions, we check that the
currently-provided language options are consistent with the options
used to compile the PCH file. If they are not, we emit a diagnostic
and ignore the PCH file.

Chris Lattner 2916a482fb add a new PP_MACRO_NAME hack so that I can test object-like macros.

 2009-04-10 18:08:30 +00:00
Chris Lattner baa52f47c1 emit function-like and object-like macros to the PCH file. 
Note that we don't do anything useful with identifier infos yet
and don't emit the tokens that the macros are defined to.

llvm-svn: 68797
 2009-04-10 18:00:12 +00:00
Douglas Gregor 1e9bf3bad4 Various minor fixes to PCH reading and writing, with general
