Registering alias of functions on ppc64 seems to be broken since this
commit:
11f5dba Bug 19885 - Cannot associates a function DIE to a symbol on powerpc64
This is because the ppc64-specific code tries to register a symbol
alias that was already registered as an alias by the arch-agnostic
code.
This patch fixes that.
* src/abg-dwarf-reader.cc (read_context::load_symbol_maps): While
filling the ppc64-specific "function-entry-address => symbol" map,
if we stumble accross a function-entry-address that belongs to an
alias of 'symbol', then assume the alias must have been registered
as an alias already, by the platform-agnostic code. Do not try to
register the alias again.
* tests/data/Makefile.am: Add the new test input binaries to the
source distribution.
* tests/data/test-diff-dwarf/libtest36-ppc64-aliases-v0.so: New
binary test input.
* tests/data/test-diff-dwarf/libtest36-ppc64-aliases-v1.so: Likewise.
* tests/data/test-diff-dwarf/test36-ppc64-aliases-report-0.txt:
New test reference output.
* tests/data/test-diff-dwarf/test36-ppc64-aliases-v0.cc: Source
code for the new binary test input above.
* tests/data/test-diff-dwarf/test36-ppc64-aliases-v1.cc: Likewise.
* tests/test-diff-dwarf.cc: Add the new test input to the list of
test inputs considered by this test harness.
