2022-11-22Revert "configure: Implement --enable-host-pie"Marek Polacek3-54/+4
This reverts commit 251c72a68af3a8b0638705b73ef120ffdf0053eb.
2022-11-22configure: Implement --enable-host-pieMarek Polacek3-4/+54
This patch implements the --enable-host-pie configure option which makes the compiler executables PIE. This can be used to enhance protection against ROP attacks, and can be viewed as part of a wider trend to harden binaries. It is similar to the option --enable-host-shared, except that --e-h-s won't add -shared to the linker flags whereas --e-h-p will add -pie. It is different from --enable-default-pie because that option just adds an implicit -fPIE/-pie when the compiler is invoked, but the compiler itself isn't PIE. Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH regressions. When building the compiler, the build process may use various in-tree libraries; these need to be built with -fPIE so that it's possible to use them when building a PIE. For instance, when --with-included-gettext is in effect, intl object files must be compiled with -fPIE. Similarly, when building in-tree gmp, isl, mpfr and mpc, they must be compiled with -fPIE. I plan to add an option to link with -Wl,-z,now. ChangeLog: * Makefile.def: Pass $(PICFLAG) to AM_CFLAGS for gmp, mpfr, mpc, and isl. * Makefile.in: Regenerate. * Makefile.tpl: Set PICFLAG. * configure.ac (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate. c++tools/ChangeLog: * Makefile.in: Rename PIEFLAG to PICFLAG. Set LD_PICFLAG. Use it.

Remove NO_PIE_CFLAGS and NO_PIE_FLAG. Pass LD_PICFLAG to ALL_LINKERFLAGS. Use the "pic" build of libiberty if --enable-host-pie. * configure.ac (--enable-host-shared): Don't set PICFLAG here.

2022-06-03libcody: fix nonportable shell code in revision.stamp build ruleAlexandre Oliva1-2/+2
Two non-portable shell constructs have been long present in libcody's build rule for revision.stamp: $() instead of ``, and += to append to a shell variable. The former seems to work even when bash is operating as /bin/sh, but += doesn't, and it ends up trying to run revision+=M as a command name, and issuing an error as that command is (hopefully) not found. This patch replaces both constructs with more portable ones. for libcody/ChangeLog * Makefile.in (revision.stamp): Replace $() and += with more portable shell constructs.

2022-03-18libcody: Do not use a dummy port number in getaddrinfo().Iain Sandoe1-4/+2
the getaddrinfo() requires either a non-null name for the server or a port service / number. In the code that opens a connection we have been calling this with a dummy port number of "0". Unfortunately this triggers a bug in some BSD versions and OSes importing that code. In this part of the code we do not really need a port number, since it is not reasonable to open a connection to an unspecified host. Setting hints info field to 0, and the servname parm to nullptr works around the BSD bug in this case. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libcody/ChangeLog: * netclient.cc (OpenInet6): Do not provide a dummy port number in the getaddrinfo() call.

> The -enable-checking configure code in libcody didn't play well with > us. This just uses libcpp's configurey for that piece. This doesn't set is_release anywhere, which means when --enable-checking* or --disable-checking isn't specified, it always treats it as --enable-checking=yes, while the normal gcc behavior is treat only trunk as --enable-checking=yes and treat release branches as --enable-checking=release by default. On the other side, nothing uses those ac_assert_checking and ac_valgrind_checking variables, so it is a waste to compute those. 2020-12-16 Jakub Jelinek <jakub@redhat.com> * configure.ac: Compute is_release. (NMS_ENABLE_CHECKING): Simplify but not computing ac_assert_checking and ac_valgrind_checking the code doesn't use. * configure: Regenerated.
2020-12-16libcody: Fix build for older GCC versionsJonathan Wakely1-2/+13
Before CWG DR 1955 the controlling expression for an #elif must be syntactically correct, meaning this won't compile with C++11 compilers such as gcc 4.8: The solution is to define __has_include(X) as 0 for compilers that don't support it. The second problem is that when <source_location> is found, it is used without the std:: qualification. libcody/ChangeLog: * internal.hh: Define fallback macros for __has_builtin and __has_include. Use __has_builtin for __builtin_FILE and __builtin_LINE. Define alias for std::source_location.
