While profiling the DWARF reader, I noticed that partial_die_info::read creates a vector to store attributes. However, the vector is not needed, as this code only processes a single attribute at a time. This patch removes the vector. On my machine, this improves the time of "./gdb ./gdb" from 2.22 seconds to 1.92 seconds (mean times over 10 runs). Note that the attribute is initialized by read_attribute, so it does not need any special initialization. Avoiding this also improves performance a bit. Tested on x86-64 Fedora 30. I'm checking this in. gdb/ChangeLog 2020-04-02 Tom Tromey <tromey@adacore.com> * dwarf2/read.c (partial_die_info::read): Do not create a vector of attributes.
