+lttng_ust_elf unit tests
+========================
+
+This is a series of unit tests for LTTng UST's ELF parser. The parser
+is used to retrieve memory size, build ID, and debug link information
+from ELF objects (standalone executable or shared object) for base
+address statedump or dl events.
+
+The parser should technically be able to read ELF files from any 32-
+or 64-bit architecture, little- or big- endian.
+
+However, to restrict the total amount of testing done, only 4
+architectures representing all combinations of bitness and endianness
+are currently tested:
+
+* x86
+* x86_64
+* armeb
+* aarch64_be
+
+For each architecture, there is a corresponding subdirectory under
+`data`, and each of these directories contains exactly 2 files,
+`main.elf` and `main.elf.debug`.
+
+The ELF files are generated from the trivial `main.c` program found in
+`data/`, using GNU toolchains. The program contains a static array in
+order to ensure the creation of a `.bss` section in the ELF file,
+which is one of the multiple factors leading to different file and
+in-memory size.
+
+The program is compiled with `gcc -g main.c -o main.elf`. On certain
+architectures, it is necessary to explicitly specify the
+`-Wl,--build-id=sha1` flags to include a build ID in the resulting
+executable.
+
+The debug information bundled in `main.elf` is then copied into
+`main.elf.debug` and stripped, and a debug link pointing to this file
+is added to the executable. The commands used are as follow:
+
+ $ objcopy --only-keep-debug main.elf main.elf.debug
+ $ strip -g main.elf
+ $ objcopy --add-gnu-debuglink=main.elf.debug main.elf
+
+There is also a series of tests used to check detection of
+position-independent code (PIC). These tests use three pre-compiled
+ELF files found under `data/pic/`, namely `hello.exec`, `hello.pie`,
+and `hello.pic`. These can be re-generated using the files `hello.c`
+and `libhello.c`, with the following commands:
+
+ $ gcc hello.c -o hello.exec
+ $ gcc hello.c -fPIC -pie -o hello.pie
+ $ gcc -shared -o hello.pic -fPIC libhello.c
