IWYU for llvm-config.h in llvm, additions. See r331124 for how I made a list of files missing the include. I then ran this Python script: for f in open('filelist.txt'): f = f.strip() fl = open(f).readlines() found = False for i in xrange(len(fl)): p = '#include "llvm/' if not fl[i].startswith(p): continue if fl[i][len(p):] > 'Config': fl.insert(i, '#include "llvm/Config/llvm-config.h"\n') found = True break if not found: print 'not found', f else: open(f, 'w').write(''.join(fl)) and then looked through everything with `svn diff \| diffstat -l \| xargs -n 1000 gvim -p` and tried to fix include ordering and whatnot. No intended behavior change. llvm-svn: 331184 2018-04-30 22:59:11 +08:00			`#include "llvm/Config/llvm-config.h"`
Use the new script to sort the includes of every file under lib. Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131 2012-12-04 00:50:05 +08:00			`#include "llvm/Support/Valgrind.h"`

Rename Unix/.cpp and Win32/.cpp to have a *.inc suffix so that the silly gdb debugger doesn't get confused on which file it is reading (the one in lib/System or the one in lib/System/{Win32,Unix}) llvm-svn: 19426 2005-01-10 07:29:00 +08:00			`#include "Unix/Memory.inc"`

s/LLVM_ON_WIN32/_WIN32/, llvm LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the default macro instead of a reinvented one. See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev. No intended behavior change. This moves over all uses of the macro, but doesn't remove the definition of it in (llvm-)config.h yet. llvm-svn: 331127 2018-04-29 08:45:03 +08:00			`#ifdef _WIN32`
