Second try at making direct object emission produce the same results
...
as llc + llvm-mc. This time ELF is not changed and I tested that llvm-gcc
bootstrap on darwin10 using darwin9's assembler and linker.
llvm-svn: 121006
2010-12-06 17:27:56 +00:00
1c8ac8f027
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.
llvm-svn: 120889
2010-12-04 03:21:47 +00:00

Next step: Only pad debug_line when the target is darwin. Add a FIXME to avoid

doing that if the target is darwin10 or newer.
This fixes
*) Direct object emission was producing objects without the workaround on
darwin9.
*) Assembly printing was producing objects with the workaround on linux.

It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.

be as efficient as we have to use DW_LNE_set_addres, but at least

llvm-gcc is able to produce debug_line sections without needing an

Add a InitSections method to the streamer interface.
...
The ELF implementation now creates text, data and bss to match the gnu as
behavior.
The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.
A nice benefit is that -n is not required anymore when producing
ELF files.

WriteNopData() changing the output. There are many FIXMEs in this patch which

Add the ability for MCStreamer to emit comments on the same line as directives.
...
Switch over the asm-verbose comment for double values to use it. We now get:
_x:
.long 343597384 ## double 1.231200e+02
.long 1079953326
For example, note that the comment is on the same line as the .long. Woo.
