This is the first change to add Linux support to dr_create_memory_dump. The memory dump is written in ELF format and saved under the logs directory following the Windows example in win32/os.c. Add a new test, memory_dump_test, to test dr_create_memory_dump for X64 Linux. Issue: #7046

Set postcmd to use "readelf -a" to dump the contents of Linux memory dump file. Replace suite/tests/client-interface/memory_dump_test.expect with suite/tests/client-interface/memory_dump_test.templatex which validates the contents of the output of "readelf -a". Issue: #7046

) Add loadable segment program headers to memory dump file. Set the entry point address in the ELF file header based on the PC value. Update the unit test to check loadable segment program header. Here's the output of readelf -l using the unit test output from a X86 machine: $ readelf -l logs/simple_app.3281609.00000000.elf Elf file type is CORE (Core file) Entry point 0x7fcd05936320 There are

…re file. (#7144) Align loadable segments to page size in the core file. Based on https://man7.org/linux/man-pages/man5/elf.5.html: p_align This member holds the value to which the segments are aligned in memory and in the file. Loadable process segments must have congruent values for p_vaddr and p_offset, modulo the page size. Values of zero and one mean no alignment is required. Otherwise, p_align should be a positive, integral power of two, and p_vaddr should equal p_offset, modulo p_align. The loabable segments alignment applies to both the address and the offset in the core file.
