Bug ID: 23066
Summary: undefined reference to
`x86_in_indirect_branch_thunk(unsigned long, char
const**, int, int)'
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: patrick at monnerat dot net
Target Milestone: ---

Since commit 1d509aa that introduces new file x86-tdep.c, the error in summary
occurs at gdb compile time because x86-tdep.c is neither compiled nor linked.

Build platform: linux x86_64.
configure command: ./configure --prefix=/usr/. --libdir=/usr/lib64
--disable-binutils --disable-gas --disable-gprof --disable-gold --disable-ld
--disable-elfcpp --disable-zlib --enable-sim --disable-rpath
--with-gdb-datadir=/usr/share/gdb --with-jit-reader-dir=/usr/lib64/gdb
--with-separate-debug-dir='/usr/lib/debug' --with-expat --with-python
--without-libunwind --without-babeltrace --with-lzma --enable-inprocess-agent
--with-auto-load-dir='/usr/share/gdb/auto-load'

If I add option '--enable-targets=all' to the configure command, the build
succeeds.
