[Constant Hoisting] Change the algorithm to only track constants for instructions.

users, which could be instructions and constant expressions. This change only
tracks the constants for instructions, but constant expressions are indirectly
covered too. If an operand is an constant expression, then we look through the
expression to find anny expensive constants.

The algorithm keep now track of the instruction and the operand index where the
constant is used. This allows more precise hoisting of constant materialization
code for PHI instructions, because we only hoist to the basic block of the
incoming operand. Before we had to find the idom of all PHI operands and hoist
the materialization code there.

This also makes updating of instructions easier. Before we had to keep track of
the original constant, find it in the instructions, and then replace it. Now we
can just simply update the operand.

Add an option to MCJIT to have it forward all sections to the
RTDyldMemoryManager, regardless of whether it thinks they're "required for

Currently, RuntimeDyld only passes sections that are "required for execution"
to the RTDyldMemoryManager, and takes "required for execution" to mean exactly
"contains symbols or relocations". There are two problems with this:
(1) It can drop sections with anonymous data that is referenced by code.
(2) It leaves the JIT client no way to inspect interesting sections that aren't
    actually required to run the program (e.g dwarf sections).

A test case is still in the works.

Future work: We may want to replace this with a generic section filtering
mechanism, but that will require more consideration. For now, this flag at least
allows clients to volunteer to do the filtering themselves.

    Use the range machinery for DW_AT_ranges and DW_AT_high/lo_pc.

    ranges if we are:

    a) In the same section, and
    b) In the same enclosing CU.

    This means we have more fine grained ranges for compile units, and fewer
    ranges overall when we have multiple functions in the same CU
    adjacent to each other in the object file.

    Also remove all of the earlier hacks around this functionality for
    function sections etc. Also update all of the testcases to take into
    account the merging functionality.

with a fix for location entries in the debug_loc section:

Make sure that debug loc entries are relative to the low_pc
of the compile unit. This means that when we only have a single
range that the offset should be just relative to the low_pc
of the unit, for multiple ranges for a CU this means that we'll be
relative to 0 which we emit along with DW_AT_ranges.

This mostly shows up with linked binaries, so add a testcase with
multiple CUs so that our location is going to be offset of a CU
with a non-zero low_pc.

10 years agoLook through variables when computing relocations.
Rafael Espindola [Thu, 20 Mar 2014 02:12:01 +0000 (02:12 +0000)]
Look through variables when computing relocations.

Given

bar = foo + 4
.long bar

MC would eat the 4. GNU as includes it in the relocation. The rule seems to be
that a variable that defines a symbol is used in the relocation and one that
does not define a symbol is evaluated and the result included in the relocation.

Fixing this unfortunately required some other changes:

* Since the variable is now evaluated, it would prevent the ELF writer from
  noticing the weakref marker the elf streamer uses. This patch then replaces
  that with a VariantKind in MCSymbolRefExpr.

* Using VariantKind then requires us to look past other VariantKind to see

.weakref bar,foo
call bar@PLT

  doing this also fixes

zed = foo +2
call zed@PLT

  so that is a good thing.

* Looking past VariantKind means that the relocation selection has to use
  the fixup instead of the target.

This is a reboot of the previous fixes for MC. I will watch the sanitizer
buildbot and wait for a build before adding back the previous fixes.

Use the range machinery for DW_AT_ranges and DW_AT_high/lo_pc.

This commit moves us from a single range per subprogram to extending
ranges if we are:

a) In the same section, and
b) In the same enclosing CU.

This means we have more fine grained ranges for compile units, and fewer
ranges overall when we have multiple functions in the same CU
adjacent to each other in the object file.

Also remove all of the earlier hacks around this functionality for
function sections etc. Also update all of the testcases to take into
account the merging functionality.
