Jason Molenda a1609ff658 Jim unintentionally had the gdb-format specifiers falling through
after r276132 so that 'x/4b' would print out a series of 4 8-byte
quantities.  Fix that, add a test case.

Hafiz Abid Qadeer 68d7f37d26 Fix a bug where lldb does not respect the packet size.
Summary: LLDB was using packet size advertised by the target as the max memory size to write in one go. It is wrong because packets have other overhead apart from memory payload. Also memory transferred through 'm' and 'M' packets needs 2 bytes in packet to transfer 1 of memory.

It turns out things are not as simple as I hoped. sys/personality.h

all platform levels.

Pavel Labath 1d5855b107 Replace getcwd with the llvm equivalent
Summary:
getcwd() is not available (well.. um.. deprecated?) on windows, and the way
PosixApi.h is providing it causes strange compile errors when it's included in
the wrong order. The best way to avoid that is to just not use chdir.

This replaces all uses of getcwd in generic code. There are still a couple of
more uses, but these are in platform-specific code.

chdir() is causing a similar problem, but for that there is no llvm equivalent
for that (yet).

Hafiz Abid Qadeer 4687db0e09 Provide a substitute to load command of gdb.
For bare-metal targets, lldb was missing a command like 'load' in gdb
which can be used to create executable image on the target. This was
discussed in
http://lists.llvm.org/pipermail/lldb-dev/2016-December/011752.html

This commits adds an option to "target module load" command to provide
that functionality. It does not set the PC to entry address which will
be done separately.

Pavel Labath 107d9bbd6c Add a more succinct logging syntax
This adds the LLDB_LOG macro, which enables one to write more succinct log
statements.
if (log)
  log->Printf("log something: %d", var);
becomes
LLDB_LOG(log, "log something: {0}, var);

The macro still internally does the "if(log)" dance, so the arguments are only
evaluated if logging is enabled, meaning it has the same overhead as the
previous syntax.

Additionally, the log statements will be automatically prefixed with the file
and function generating the log (if the corresponding new argument to the "log
enable" command is enabled), so one does not need to manually specify this in
the log statement.

It also uses the new llvm formatv syntax, which means we don't have to worry
about PRIx64 macros and similar, and we can log complex object (llvm::StringRef,
lldb_private::Error, ...) more easily.

The NDK cmake toolchain file defines CMAKE_SYSTEM_NAME=Android, so switch the

Pavel Labath 0cfd7dc9ea Remove a couple of Stream flags
Summary:
I came across this while trying to understand what Log::Debug does. It turns out
it does not do anything, as there is no instance of someone setting a debug flag
on a stream. The same is true for the Verbose and AddPrefix flags. Removing
these will enable some cleanups in the Logging class, and it brings us closer
towards the long term goal of standardizing on llvm stream classes.

I have removed these flags and all code the code which tested for their
presence -- there wasn't much of it, mostly in SymbolFileDWARF, which is
probably going away at some point anyway.

The eBinary flag still has some users, so I am letting it life for the time
being.

Summary:
To implement wide character reading, editline was mixing FILE*-based access with

fragile. Here, I replace it with one which uses only a Connection-based reads.
The code is somewhat longer as I had to read characters one by one to detect the
end of the multibyte sequence.

I've verified that international characters still work in lldb command line on
OSX.

Howard Hellyer 9434690ab7 Simplify reading of Linux notes to correctly handle endianess.
Summary:
This patch changes and simplifies the way notes are read from Linux Elf cores.
The current implementation copies the bytes from the notes directly over the lldb structure for 64 bit cores and reads field by field for 32 bit cores. Reading the bytes directly only works if the endianess of the core dump and the platform that lldb are running on matches. The case statements for s390x and x86_64 would would only work on big endian systems and little endian systems respectively. That meant that x86_64 generally worked but s390x didn't unless you were on s390x or another big endian platform.
This patch just reads field by field on all platform and updates the field by field version to allow for those fields which are word size instead of fixed size. It should also slightly simplify adding support for a new Linux platform.

This patch also re-enables the s390x test case in TestLinuxCore.py on all non-s390x platforms as it now passes.

If you were stepping through code where the dynamic type of a variable would change the value and its children, or a synthetic type (like say for a std::vector<int>), the variable view wouldn't update.

Luke Drummond f5bb1d6c4e Expression evaluation for overloaded C functions (redux)
This is a redux of [Ewan's patch](https://reviews.llvm.org/D17957) , refactored
to properly substitute primitive  types using a hook in the itanium demangler,
and updated after the previous patch went stale

The new `SubsPrimitiveParmItanium` function takes a symbol name and replacement
primitive type parameter as before but parses it using the FastDemangler, which
has been modified to be able to notify clients of parse events (primitive types
at this point).

Additionally, we now use a `set` of `ConstStrings` instead of a `vector` so
that we don't try and resolve the same invalid candidate multiple times.
