[GOLD] PowerPC tls_get_addr_optimize This implements the special __tls_get_addr_opt call stub for powerpc gold that returns __thread variable addresses without actually making a call to __tls_get_addr in most cases. Shared libraries that are loaded at program load time (ie. dlopen is not used) have a known layout for their __thread variables, and thus DTPMOD64/DPTREL64 pairs describing those variables can be set up by ld.so for the __tls_get_addr_opt call stub fast exit. Ref https://sourceware.org/ml/libc-alpha/2015-03/msg00626.html I really, really wish I'd used a differently versioned __tls_get_addr symbol than the base symbol to indicate glibc support for the optimized call, rather than having glibc export __tls_get_addr_opt. A lot of the messing around here, flipping symbols from __tls_get_addr to __tls_get_addr_opt, is caused by that decision. About the only benefit is that a user can see at a glance that their disassembled code is calling __tls_get_addr via the fancy call stub.. Anyway, we need references to __tls_get_addr to seem like they were to __tls_get_addr_opt, and in cases like the tsan interceptor, a definition of __tls_get_addr to seem like one of __tls_get_addr_opt as well. That's the reason for Symbol::clear_in_reg and Symbol_table::clone, and why symbols are substituted in Scan::global and other places dealing with dynamic linking. elfcpp/ * elfcpp.h (DT_PPC_OPT): Define. * powerpc.h (PPC_OPT_TLS): Define. gold/ * options.h (tls_get_addr_optimize): New option. * symtab.h (Symbol::clear_in_reg, clone): New functions.

[GOLD] PowerPC recreate eh_frame for stubs on each relax pass There is a very small but non-zero probability that a stub group contains stubs on one relax pass, but does not on the next. In that case we would get an FDE covering a zero length address range. (Actually, it's even worse. Alignment padding for stubs can mean the address for the non-existent stubs is past the end of the original section to which stubs are attached, and due to the way do_plt_fde_location calculates the length we can get a negative length.) Fixing this properly requires removing the FDE. Also, I have been implementing the __tls_get_addr_opt support for gold, and that stub needs something other than the default FDE. The necessary FDE will depend on the offset to the __tls_get_addr_opt stub, which of course can change during relaxation. That means at the very least, rewriting the FDE on each pass, possibly changing the FDE size. I think that is better done by completely recreating PLT eh_frame FDEs. * ehframe.cc (Fde::operator==): New.
