* IWYU for llvm-config.h in llvm, additions.Nico Weber2018-04-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* [DWARF] Don't attempt to parse line tables at invalid offsetsJames Henderson2018-03-081-0/+42
Whilst working on improvements to the error handling of the debug line parsing code, I noticed that if an invalid offset were to be specified in a call to getOrParseLineTable(), an entry in the LineTableMap would still be created, even if the offset was not within the section range. The immediate parsing attempt afterwards would fail (it would end up getting a version of 0), and thereafter, any subsequent calls to getOrParseLineTable or getLineTable would return the default- constructed, invalid line table. In reality, we shouldn't even attempt to parse this table, and we should always return a nullptr from these two functions for this situation. I have tested this via a unit test, which required some new framework for unit testing debug line. My plan is to add quite a few more unit tests for the new error reporting mechanism that will follow shortly, hence the reason why the supporting code for the tests are written the way they are - I intend to extend the DwarfGenerator class to support generating debug line. At that point, I'll make sure that there are a few positive test cases for this and the parsing code too.
