From 5fdcc3c931b70204fd8c491afa66f57f8428490f Mon Sep 17 00:00:00 2001 From: David Srbecky Date: Tue, 19 Jan 2016 14:33:43 +0000 Subject: Add option to generate compressed backtrace info. Add flag --generate-mini-debug-info which generates LZMA compressed .symtab and .debug_frame, which are sufficient to print java backtraces in libunwind. If enabled, it increases the size of boot.oat by about 3.5%.
