Duncan Sands 5c65cb4633 Fix PR1836: in the interpreter, read and write apints 
using the minimum possible number of bytes.  For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before.  For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness).  Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this.  Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

Anton Korobeynikov 657be86229 And finally annotate X86-64 version of callback. 
All bad stuff from SSE version is implicitely inherited :)

Anton Korobeynikov 88e9d082d8 Provide annotation for SSE version of callback. It's even more 
broken, because doesn't mark xmm regs properly

Anton Korobeynikov 81e9dc4af7 Annotate JIT callback function with call frame infromation. 
This will allow us (theoretically) to unwind through JITer.
The code wasn't verified, so I'm pretty sure offsets are wrong :)

Duncan Sands 81b25817f9 It looks like this has been broken for some time -

Gordon Henriksen 71183b6739 Adding a collector name attribute to Function in the IR. These 
methods are new to Function:

  bool hasCollector() const;
  const std::string &getCollector() const;
  void setCollector(const std::string &);
  void clearCollector();

The assembly representation is as such:

  define void @f() gc "shadow-stack" { ...

The implementation uses an on-the-side table to map Functions to 
collector names, such that there is no overhead. A StringPool is 
further used to unique collector names, which are extremely
likely to be unique per process.

Chris Lattner 3ed83c1c0f The flags on tokens indicate whether they are the start of a *physical* line, 
not the start of a logical line.  Be careful about this distinction, which 
affects when newlines are printed and when paste-avoidance happens, etc.  
This fixes PR1848, thanks to Neil for noticing this!

llvm-svn: 44743
 2007-12-09 21:11:08 +00:00
Chris Lattner 84f450789a Fix a pretty big but subtle bug counting the number of newlines to emit. 
This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

This is part of PR1848.
