libsframe: add symbol versioning Define an empty base version LIBSFRAME_0.0 and add all symbols to version LIBSFRAME_1.0. The previous release of libsframe (libsframe.so.0) did not have versioned symbols. Adding a libsframe.ver file so that future releases of the library (and its consumers) can manage the changes better. For Solaris ld, use -M mapfile command line option. libsframe does not restrict the set of exported symbols, so at this time there is no need to fall back on the libtool's -export-symbols option for platforms where some other linker (with a different command line option for symbol versioning) may be used. libsframe/ * Makefile.am: Use symbol versioning for libsframe. * Makefile.in: Regenerated. * configure: Check for Solaris ld. * configure.ac: Regenerated. * libsframe.ver: New file.

sframe: bfd: gas: ld: format bump to SFrame version 2 SFrame version 2 encodes the size of repetitive insn block explicitly in the format. Add information in the SFrame FDE to convey the size of the block of repeating instructions. This information is used only for SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK. Introduce two extra bytes for padding: this ensures that the memory accesses to the members of the SFrame Frame Descriptor Entry (FDE) are naturally aligned. gas generates SFrame section with version SFRAME_VERSION_2 by default. libsframe provides two new APIs to: - get an SFrame FDE data from the decoder context, and - add an SFrame FDE to the encoder context. The additional argument (for rep_block_size) is useful for SFrame FDEs where FDE type is SFRAME_FDE_TYPE_PCMASK. The linker will generate the output SFrame sections in the SFRAME_VERSION_2 format. If the input sections offered to the linker are not all in the SFRAME_VERSION_2 format, the linker issues an error to the user. objdump/readelf will show the following message to the user if .sframe section in SFRAME_VERSION_1 format is seen: "No further information can be displayed. SFrame version not supported." In other words, like the rest of the binutils, only the current SFrame format version, i.e., SFRAME_VERSION_2 is supported by the textual dump facilities. bfd/ * elf-sframe.c (_bfd_elf_merge_section_sframe): Generate an output SFrame section with version SFRAME_VERSION_2.
