From: Omar Sandoval <osan...@fb.com> Hello,
This series is a followup to my RFC [1]. Compared to the RFC patches, this series adds patch 1 as a trivial cleanup, patch 3 to fix an oversight in the RFC w.r.t. PIC object files sneaking into libdw.a, and patch 5 to implement my suggestion for reducing the size of the elfutils binaries by exporting libebl symbols from libdw.so. After this series, libebl no longer uses dlopen() to find backends, and the total size of the package is actually smaller than before (2.1 MB): 44K ./libasm/libasm.so 672K ./libdw/libdw.so 120K ./libelf/libelf.so 52K ./src/nm 28K ./src/size 60K ./src/strip 116K ./src/elflint 28K ./src/findtextrel 36K ./src/addr2line 32K ./src/elfcmp 40K ./src/objdump 32K ./src/strings 48K ./src/ar 60K ./src/unstrip 36K ./src/stack 40K ./src/elfcompress 32K ./src/ranlib 236K ./src/readelf 1.7M total If there are no issues, I'd love to see this merged, as it greatly simplifies using libdw in environments where dlopen() is not supported.
