| | | | | | | | | | | | | | | | | | We only need a few constants and one structure definition from linux/bpf. Just define those in a local lib/bpf.h file. This makes sure the bpf disassembler is always build and included even when elfutils is build on older GNU/Linux systems (and even on other platforms).

| * Avoid double-including config.hUlf Hermann2017-05-023-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | config.h doesn't have include guards, so including it twice is bad. We deal with this by checking for PACKAGE_NAME, but only in some places. Once we start using gnulib, we will need to include config.h before any gnulib-generated headers. This is problematic if we include it transitively through our own private headers. In order to set a clear rule about inclusion of config.h, it is now included in every .c file as first header, but not in any header. This will definitely avoid double-inclusion and satisfy the condition that it has to be included before gnulib headers. It comes at the price of adding some redundancy, but there is no clean way to avoid this. Signed-off-by: Ulf Hermann <[email protected]>
* | Provide build rules for a compatibility libraryUlf Hermann2017-05-083-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | We need to export open(), close(), malloc(), and free() from the C library we are using so that we can handle resources passed to and from elfutils correctly. For example, on Windows, calling free() on memory malloc()'d with a different C library will not work. In addition, having __cxa_demangle from the GNU libstdc++ available is very helpful, so we include that, too.

| | | | | | | | | | | | | | | | | | | | The mechanism of moving argp_program_version_hook and argp_program_bug_address to .rodata is not portable and two pointers per program are not worth the effort to make it portable.

| | | | | | | | | | | | | | | | | | | | In general we need to use ';' as path separator and '\' and directory separator on windows. The shell will automatically translate paths to some extent, but we have to call "pwd -W" rather than plain "pwd" to get something useful.

* lib: Avoid the hash-lookup division if possibleJosh Stone2013-12-132-2/+7
| | | | | | | | | | | | | For Dwarf_Abbrev codes, the most common case is that they're packed at the low end, saving uleb128 encoding size. Since the hash table is always resized to be no more than 90% full, those codes are always less than the table size, and dividing for the remainder is unnecessary. Dwarf_Dies are frequently created anew, and need to find abbrev each time, so even that one division becomes a noticeable hotspot. This patch adds a branch to avoid it, which is very predictable for the CPU. Signed-off-by: Josh Stone <[email protected]>
