+# Note [Disable automatic stripping] |
115 |
+# Disabling automatic stripping for a few reasons: |
116 |
+# - portage's attempt to strip breaks non-native binaries at least on |
117 |
+# arm: bug #697428 |
118 |
+# - portage's attempt to strip libpthread.so.0 breaks gdb thread |
119 |
+# enumeration: bug #697910. This is quite subtle: |
120 |
+# * gdb uses glibc's libthread_db-1.0.so to enumerate threads. |
121 |
+# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols |
122 |
+# via 'ps_pglobal_lookup' symbol defined in gdb. |
123 |
+# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all |
124 |
+# known symbols in 'libpthread.so.0'. Specifically 'nptl_version' |
125 |
+# (unexported) is used to sanity check compatibility before enabling |
126 |
+# debugging. |
127 |
+# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint |
128 |
+# * normal 'strip' command trims '.symtab' |
129 |
+# Thus our main goal here is to prevent 'libpthread.so.0' from |
130 |
+# losing it's '.symtab' entries. |
131 |
+# As Gentoo's strip does not allow us to pass less aggressive stripping |
132 |
+# options and does not check the machine target we strip selectively. |
133 |
+ |
134 |
+# We need a new-enough binutils/gcc to match upstream baseline. |
135 |
+# Also we need to make sure our binutils/gcc supports TLS, |
136 |
+# and that gcc already contains the hardened patches. |
137 |
+# Lastly, let's avoid some openssh nastiness, bug 708224, as |
138 |
+# convenience to our users. |
