ELFObjectFile.h: Silence warning on Windows

The compiler was warning about using | on a uintptr_t and bool:

  Object/ELFObjectFile.h(131) : warning C4805: '|' : unsafe
  mix of type 'uintptr_t' and type 'bool' in operation

I think the warning might be useful in other cases, so I added
a cast instead of disabling it altogether.

10 years agoFix assembling of Thumb2 branch instructions.
Mihai Popa [Fri, 9 Aug 2013 10:38:32 +0000 (10:38 +0000)]
Fix assembling of Thumb2 branch instructions.

The long encoding for Thumb2 unconditional branches is broken.
Additionally, there is no range checking for target operands; as such
for instructions originating in assembly code, only short Thumb encodings
are generated, regardless of the bitsize needed for the offset.

Adding range checking is non trivial due to the representation of Thumb
branch instructions. There is no true difference between conditional and
unconditional branches in terms of operands and syntax - even unconditional
branches have a predicate which is expected to match that of the IT block
they are in. Yet, the encodings and the permitted size of the offset differ.

Due to this, for any mnemonic there are really 4 encodings to choose for.

The problem cannot be handled in the parser alone or by manipulating td files.
Because the parser builds first a set of match candidates and then checks them
one by one, whatever tablegen-only solution might be found will ultimately be
dependent of the parser's evaluation order. What's worse is that due to the fact
that all branches have the same syntax and the same kinds of operands, that
order is governed by the lexicographical ordering of the names of operand
classes...

To circumvent all this, any necessary disambiguation is added to the instruction
validation pass.

10 years agoAdd support for linking against a curses library when available and
Chandler Carruth [Wed, 7 Aug 2013 08:47:36 +0000 (08:47 +0000)]
Add support for linking against a curses library when available and
using it to detect whether or not a terminal supports colors. This
replaces a particularly egregious hack that merely compared the TERM
environment variable to "dumb". That doesn't really translate to
a reasonable experience for users that have actually ensured their
terminal's capabilities are accurately reflected.

This makes testing a terminal for color support somewhat more expensive,
but it is called very rarely anyways. The important fast path when the
output is being piped somewhere is already in place.

The global lock may seem excessive, but the spec for calling into curses
is *terrible*. The whole library is terrible, and I spent quite a bit of
time looking for a better way of doing this before convincing myself
that this was the fundamentally correct way to behave. The damage of the
curses library is very narrowly confined, and we continue to use raw
escape codes for actually manipulating the colors which is a much sane
system than directly using curses here (IMO).

If this causes trouble for folks, please let me know. I've tested it on
Linux and will watch the bots carefully. I've also worked to account for
the variances of curses interfaces that I could finde documentation for,
but that may not have been sufficient.
