Bug ID: 17961
Summary: MINIMAL_SYMBOL_HASH_SIZE needs to scale
Product: gdb
Version: HEAD
Status: NEW
Keywords: performance
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: dje at google dot com
I was profiling gdb trying to see why "break (anonymous namespace):foo" was
slow.
The problem turned out to be due to a couple of reasons.
One of them is that this program is big.
Big as in "nm $binary | wc" shows ~4M symbols.
Currently MINIMAL_SYMBOL_HASH_SIZE is the constant 2039.
This value needs to scale.
