There are more than one paths to where the frame information is emitted. Place
the call to generateCompactUnwindEncodings() into the method which outputs the
frame information, thus ensuring that the encoding is there for every path. This
involved threading the MCAsmBackend object through to this method.

This is dead code since PIC16 was removed in 2010. The result was an odd mix,

zero (most of the object streamer for example).

c1f4a4b2640dfc871bacacef53a95f1c96a9fe48 12-Jun-2013 Ulrich Weigand <ulrich.weigand@de.ibm.com> [MC/DWARF] Support .debug_frame / .debug_line code alignment factors

I've been comparing the object file output of LLVM's integrated
assembler against the external assembler on PowerPC, and one
area where differences still remain are in DWARF sections.

In particular, the GNU assembler generates .debug_frame and
.debug_line sections using a code alignment factor of 4, since
all PowerPC instructions have size 4 and must be aligned to a
multiple of 4. However, current MC code hard-codes a code
alignment factor of 1.

This patch changes this by adding a "minimum instruction alignment"
data element to MCAsmInfo and using this as code alignment factor.

This requires passing a MCContext into MCDwarfLineAddr::Encode
and MCDwarfLineAddr::EncodeAdvanceLoc. Note that one caller,
MCDwarfLineAddr::Write, didn't actually have that information
available. However, it turns out that this routine is in fact
never used in the whole code base, so the patch simply removes
it. If it turns out to be needed again at a later time, it
could be re-added with an updated interface.

It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

I know what would be cool! We should align the compact unwind section because
aligned data access is faster.

Compact unwind has an encoding for when we're not able to generate compact
unwind and must generate an EH frame instead. Track that, but still emit that CU
encoding.

We now emit a line table for each compile unit. To reduce the prologue size
of each line table, the files and directories used by each compile unit are
stored in std::map<unsigned, std::vector< > > instead of std::vector< >.

The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each
compile unit causes a huge increase of debug info. With this patch, each
prologue will only emit the files required by the compile unit.

which version of the compiler was used.

This is the first of two steps to allow us to do that. This is the llvm-mc
change to provide a method to set the AT_producer string. The second step,
coming soon to a clang near you, will have the clang driver pass the value
of getClangFullVersion() via an flag when invoking the integrated assembler
on assembly source files.

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. =]

debug info for assembly files. We were already doing the right thing when
producing debug info for C/C++.

ELF linkers don't know dwarf, so they depend on these relocations to produce
valid dwarf output.

38fdb7d9fc40e9f29c3156b6625cac8d91d562e1 10-Jan-2012 Kevin Enderby <enderby@apple.com> Various crash reporting tools have a problem with the dwarf generated for
assembly source when it generates the TAG_subprogram dwarf debug info for
the labels that have nothing between them as in this bit of assembly source:

% cat ZeroLength.s
_func1:
_func2:
nop

One solution would be to not emit the subsequent labels with the same address
and use the next label with a different address or the end of the section for
the AT_high_pc value of the TAG_subprogram.

Turns out in llvm-mc it is not possible in all cases to determine of two
symbols have the same value at the point we put out the TAG_subprogram dwarf
debug info.

So we will have llvm-mc instead of putting out TAG_subprogram's put out
DW_TAG_label's. And the DW_TAG_label does not have a AT_high_pc value which
avoids the problem.

This commit is only the functional change to make the diffs clear as to what is
really being changed. The next commit will be to clean up the names of such
things like MCGenDwarfSubprogramEntry to something like MCGenDwarfLabelEntry.

5d4918dbd116b0b5e561c431b1ea527ee1b9302a 04-Dec-2010 Rafael Espindola <rafael.espindola@gmail.com> There are two reasons why we might want to use

foo = a - b
.long foo
instead of just
.long a - b

First, on darwin9 64 bits the assembler produces the wrong result. Second,
if "a" is the end of the section all darwin assemblers (9, 10 and mc) will not
consider a - b to be a constant but will if the dummy foo is created.

Split how we handle these cases. The first one is something MC should take care
of. The second one has to be handled by the caller.

darwin9 linker, what is needed to avoid it and where to get more information.

Also make the workaround simpler. Just the regular end_sequence we normally
create is more than 4 bytes.

Tested by building cctools and ld64 from darwin9 on a darwin10 system and using
those. I checked that I was able to reproduce the bootstrap failure when
the the workaround was disabled.

be as efficient as we have to use DW_LNE_set_addres, but at least
most of the logic is shared.

llvm-gcc is able to produce debug_line sections without needing an
assembler that supports .loc.

1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
named. Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in
include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

c095793b4ab027181605c79c9808df12afe45d63 30-Sep-2010 Kevin Enderby <enderby@apple.com> This is the last major patch to implement support for the .loc directive
and output the dwarf line number tables. This contains the code to emit and
encode the dwarf line tables from the previously gathered information in the
MCLineSection objects. This contains all the details to encode the line and
address deltas into the dwarf line table.

To do this an MCDwarfLineAddrFragment has been added.

Also this moves the interface code out of Mach-O streamer into
MCDwarf so it should be useable by other object file formats.

There is now one call to be made from an MCObjectStreamer
EmitInstruction() method:
MCLineEntry::Make(this, getCurrentSection());
to create a line entry after each instruction is assembled.

And one call call to be made from an MCObjectStreamer Finish() method:
MCDwarfFileTable::Emit(this, DwarfLineSection);
when getContext().hasDwarfFiles() is true and is passed a object file specific
MCSection where to emit the dwarf file and the line tables.

This appears to now be correct for 32-bit targets, at least x86. But the
relocation entries for 64-bit Darwin needs some further work which is next
up to work on. So for now the 64-bit Mach-O target does not output the
dwarf file and line tables.
