2018-04-04Speed up direct linking with DLLs on Windows (1/2).Eric Botcazou1-3/+3
This patch deals with the auto-import feature. There are 2 versions of this feature: the original one, which was piggybacked on the OS loader with an optional help from the runtime (--enable-auto-import --enable-runtime-pseudo-reloc-v1) and is still the one mostly documented in the sources and manual; the enhanced one by Kai Tietz, which is entirely piggybacked on the runtime (--enable-auto-import --enable-runtime-pseudo-reloc-v2) and is the default for Mingw and Cygwin nowadays. The implementation is inefficient because of pe[p]_find_data_imports: for every undefined symbol, the function walks the entire set of relocations for all the input files and does a direct name comparison for each of them. This is easily fixable by using a hash-based map for v1 and a simple hash table for v2. This patch leaves v1 alone and only changes v2. It also factors out pe[p]_find_data_imports into a common function, removes old cruft left and right, and attempts to better separate the implementations of v1 and v2 in the code. ld/ * emultempl/pe.em (U_SIZE): Delete.

Build an import hash table for the pseudo-relocation support version 2. When it is built, walk the relocations only once at the end; when it is not, do not build a fixup when the symbol isn't part of an import table.
