Craig Topper 8ae1203992 [C++11] Use 'nullptr'. 
llvm-svn: 208163
 2014-05-07 06:21:57 +00:00
Lubos Lunak 4526b46ee6 write a line marker right before adding included file 
Enclosing the original #include directive inside #if 0 adds lines,
so warning/errors messages would have the line number off in
"In file included from <file>:<line>:", so add line marker to fix this.

Lubos Lunak 72cad68b30 do not use "1" for line marker for the predefines "file" either 
Similar to r207764.

Lubos Lunak 10961c0eab do not use "1" for line marker for the main file 
"1" means entering a new file (from a different one), but the main
file is not included from anything (and this would e.g. confuse -Wunused-macros
to not report unused macros in the main file, see pr15610, or also see pr18948).
The line marker is still useful e.g. if the resulting file is renamed or used
via a pipe.

Lubos Lunak 64568ca18a revert r207756 
There's nothing wrong with the change itself, but
test/Frontend/rewrite-includes-messages.c fails without another
not-yet-committed fix.

Lubos Lunak 576a0415cb do not warn about unknown pragmas in modes that do not handle them (pr9537) 
And refactor to have just one place in code that sets up the empty
pragma handlers.

Alp Toker 08c2500f9c Fix raw lex crash and -frewrite-includes noeol-at-eof failure 
Raw lexers don't have a preprocessor so we need to null check.

Alp Toker 52937abc8b Check the initial line number without going through PresumedLoc 
No practical difference in this case and would return 1 either way, but this is
more self-explanatory.

NAKAMURA Takumi ddc867985a Revert r196372, "do not warn about unknown pragmas in modes that do not handle them (pr9537)" 
It broke clang tests on some hosts with +Asserts. Seems "STDC" clashes.

Alp Toker 3dfeafd9db InclusionRewriter: Avoid duplicated BOM check 
The lexer already knows its position in the file, so use that instead of
guessing it might be 3.

Eli Friedman 9fc443aaed Address review comment on r189557. 
We need to escape filenames the same way in InclusionRewriter whether
UseLineDirective is true or false.

Eli Friedman 80e45b8cd4 Properly escape filenames in line directives. 
Fixes PR17018.  Only partial test coverage because I don't want
to try to write a test which generates a file whose name contains a newline.

Lubos Lunak 4c22f6a695 fix sometimes incorrect line numbers in -frewrite-includes mode (pr#14795) 
Every #include is surrounded by #if 0 in order to comment it out, which adds
lines. That is fixed up right after, but that all can be inside #if part
that is not processed, so fix up also after every end of a conditional part.

Argyrios Kyrtzidis d391046930 Have SourceManager::getLocForEndOfFile() point at the "EOF" location of the FileID. 
This fixes a crash due to SourceManager::getLocForEndOfFile() returning an off-by-one location
when the the FileID is for an empty file.

Benjamin Kramer b10e615c44 rewrite-includes: Rewrite __has_include(_next) to get rid of a host dependency. 
This broke e.g. compiling a crash report from a glibc system on Darwin. Sadly,
the implementation had to game the lexer a lot as we're not using a real
preprocessor here. It also doesn't handle special cases like arbitrary macros in
__has_include, but since this macro isn't common outside of clang's headers we
can get away with that.

Fixes PR14422.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers 
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Argyrios Kyrtzidis 19d78b743f For PPCallbacks::InclusionDirective() add a parameter for the module, whenever 
an inclusion directive was automatically turned into a module import, and
PPCallbacks::moduleImport() for an explicit module import.

Ted Kremenek cdf814900d Split library clangRewrite into clangRewriteCore and clangRewriteFrontend. 
This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.
