The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier.
`.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive.
Without `-LABEL`, the CHECK line can match the `Disassembly of section`
line and causes the next `CHECK-NEXT:` to fail.
```
Disassembly of section .foo:

Summary:
This is a rework of D72611, using @LINE to check that errors are
reported against the right instruction instead of adding lots of extra
*-ERR-NEXT: check lines.

Summary:
This patch applies D60551 to an additional file. In particular, the test
is currently marked XFAIL for a number of big-endian targets; however,
the failure is actually dependent on the host endianness instead. The
test actually specifies a specific target triple.

The 16 bank LDS case is complicated due to using multiple
instructions. If I attempt to write a pattern for it, the generated
selector incorrectly places the copy to m0 after the first
instruction, so that needs to be separately addressed.
Also fix not gluing the copy to m0 to the second operation in the
second half of the 16 bank lowering.
Summary:
This adds checks that the expected error was actually reported against
the correct instruction, and fixes a couple of problems that that showed
up: one incorrect W32-ERR:
v_cmp_class_f16_sdwa vcc, v1, v2 src0_sel:DWORD src1_sel:DWORD
// W64: encoding: [0xf9,0x04,0x1e,0x7d,0x01,0x00,0x06,0x06]
-// W32-ERR: error: invalid operand for instruction
+// W32-ERR: error: {{instruction not supported on this GPU|invalid operand for instruction}}
and one missing W32-ERR:
v_cmp_class_f16_sdwa s[6:7], v1, v2 src0_sel:DWORD src1_sel:DWORD
// W64: encoding: [0xf9,0x04,0x1e,0x7d,0x01,0x86,0x06,0x06]
+// W32-ERR: error: invalid operand for instruction

Summary of changes:
- simplified handling of FLAT offset: offset_s13 and offset_u12 have been replaced with flat_offset;
- provided information about error position for pre-gfx9 targets;
- improved errors handling.

Summary:
This fixes a hardware bug that makes a branch offset of 0x3f unsafe.
This replaces the 32 bit branch with offset 0x3f to a 64 bit
instruction that includes the same 32 bit branch and the encoding
for a s_nop 0 to follow. The relaxer than modifies the offsets
accordingly.

llvm-svn: 364451
Summary:
The directive defines a symbol as an group/local memory (LDS) symbol.
LDS symbols behave similar to common symbols for the purposes of ELF,
using the processor-specific SHN_AMDGPU_LDS as section index.
It is the linker and/or runtime loader's job to "instantiate" LDS symbols
and resolve relocations that reference them.
It is not possible to initialize LDS memory (not even zero-initialize
as for .bss).
We want to be able to link together objects -- starting with relocatable
objects, but possible expanding to shared objects in the future -- that
access LDS memory in a flexible way.
LDS memory is in an address space that is entirely separate from the
address space that contains the program image (code and normal data),
so having program segments for it doesn't really make sense.
Furthermore, we want to be able to compile multiple kernels in a
compilation unit which have disjoint use of LDS memory. In that case,
we may want to place LDS symbols differently for different kernels
to save memory (LDS memory is very limited and physically private to
each kernel invocation), so we can't simply place LDS symbols in a
.lds section.
Hence this solution where LDS symbols always stay undefined.
