<pre>This is a placeholder bug for a patch I will be submitting here very
shortly.
When building with GCC >= 4.8.2 on Solaris (Intel and SPARC), the
autoconf-based build system needs some adjustments. These adjustments
are not intrusive, and do not affect any other Operating System or ISA.
These changes include the use of a special Solaris Linker map file
which handles the folding/coalescing of certain specific Extended
ELF Sections for binaries compiled with -ffunction-sections -fdata-sections.
Without this linker map file, binaries built with -ffunction-sections
-fdata-sections will end up with an insane (greater than 125,000) number
of Extended ELF Section Headers (SHT_SYMTAB_SHNDX).
This linker map file is specific to the Solaris Linker. It is not needed
when linking with the GNU BFD or GNU Gold Linkers.
We have a number of clang and llvm patches for Solaris, and we have
every intention of contributing them to the project. This is just one
of several bugs with follow-up patches that I will be filing.
ETA for patches: I will start submitting patches - as attachments - this
week, within the next couple of days.</pre>
