of like “invalid constant (0x927c0) after fixup” and “unsupported relocation on

10 years agoUpdate the fragments of symbols in compressed sections.
David Blaikie [Fri, 18 Apr 2014 21:24:12 +0000 (21:24 +0000)]
Update the fragments of symbols in compressed sections.

While unnamed relocations are already cached in side tables in
ELFObjectWriter::RecordRelocation, symbols still need their fragments
updated to refer to the newly compressed fragment (even if that fragment
isn't big enough to fit the offset). Even though we only create
temporary symbols in debug info sections this comes up in 32 bit builds
where even temporary symbols in mergeable sections (such as debug_str)
have to be emitted as named symbols.

I tried a few other ways to do this but they all didn't work for various
reasons:

1) Canonicalize the MCSymbolData in RecordRelocation, nulling out the
Fragment (so it didn't have to be updated by CompressDebugSection). This
doesn't work because some code relies on symbols having fragments to
indicate that they're defined, I think.

2) Canonicalize the MCSymbolData in RecordRelocation to be "first
fragment + absolute offset" so it would be cheaper to just test and
update the fragment in CompressDebugSections. This doesn't work because
the offset computed in RecordRelocation isn't that of the symbol's
fragment, it's the passed in fragment (I haven't figured out what that
fragment is - perhaps it's the location where the relocation is to be
written). And if the fragment offset has to be computed only for this
use we might as well just do it when we need to, in
CompressDebugSection.

I also added an assert to help catch this a bit more clearly, even
though it is UB. The test case improvements would either assert fail
and/or valgrind vail without the fix, even if they wouldn't necessarily
fail the FileCheck output.

[X86] Improve buildFromShuffleMostly for AVX

For a 256-bit BUILD_VECTOR consisting mostly of shuffles of 256-bit vectors,
both the BUILD_VECTOR and its operands may need to be legalized in multiple
steps.  Consider:

(v8f32 (BUILD_VECTOR (extract_vector_elt (v8f32 %vreg0,) Constant<1>),
                     (extract_vector_elt %vreg0, Constant<2>),
                     (extract_vector_elt %vreg0, Constant<3>),
                     (extract_vector_elt %vreg0, Constant<4>),
                     (extract_vector_elt %vreg0, Constant<5>),
                     (extract_vector_elt %vreg0, Constant<6>),
                     (extract_vector_elt %vreg0, Constant<7>),
                     %vreg1))

a. We can't build a 256-bit vector efficiently so, we need to split it into
two 128-bit vecs and combine them with VINSERTX128.

b. Operands like (extract_vector_elt (v8f32 %vreg0), Constant<7>) needs to be
split into a VEXTRACTX128 and a further extract_vector_elt from the
resulting 128-bit vector.

c. The extract_vector_elt from b. is lowered into a shuffle to the first
element and a movss.

Depending on the order in which we legalize the BUILD_VECTOR and its
operands[1], buildFromShuffleMostly may be faced with:

(v4f32 (BUILD_VECTOR (extract_vector_elt
                      (vector_shuffle<1,u,u,u> (extract_subvector %vreg0, Constant<4>), undef),
                      Constant<0>),
                     (extract_vector_elt
                      (vector_shuffle<2,u,u,u> (extract_subvector %vreg0, Constant<4>), undef),
                      Constant<0>),
                     (extract_vector_elt
                      (vector_shuffle<3,u,u,u> (extract_subvector %vreg0, Constant<4>), undef),
                      Constant<0>),
                     %vreg1))

In order to figure out the underlying vector and their identity we need to see
through the shuffles.

[1] Note that the order in which operations and their operands are legalized is
only guaranteed in the first iteration of LegalizeDAG.
