While looking at the purpose of the test (to check that watchpoints are

diverged from the original intention and now it creates the threads *after* the

After some discussion, we decided both scenarios make sense, so I modify the
test to test both.

The watchpoint propagation functionality is not really debug info depenent, so
I also stop replication of this test. This brings the test's time from ~108s

correctly as libdwarves.so does not have BPF backend support yet.

handle it. More specifically, with DwarfUsesRelocationsAcrossSections
disabled, JIT compiler does not generate .debug_abbrev and Dwarf
DIE (debug info entry) processing is not happy about this.

This reverts commits r326323 and r326324.

Reason: the commits introduced a cyclic dependency in the build graph.
This happens to work with cmake, but breaks out internal integrate.

[ELF] - Don't crash on broken MEMORY declaration.

LLD crashes with broken scripts shown in testcase,
because fails to read memory regon name and accesses
MemoryRegions's element which is nullptr.
Patch fixes it.

6 years ago[ELF] - Do not remove empty sections that use symbols in expressions.

[ELF] - Do not remove empty sections that use symbols in expressions.

This is PR36515.

Currenly if we have a script like .debug_info 0 : { *(.debug_info) },
we would not remove this section and keep it in the output.
That does not work, because it is common case for
debug sections to have a zero address expression.
Patch changes behavior so that we remove only sections
that do not use symbols in its expressions.
