2022-05-03dfp.m4: Add missing license headerChristophe Lyon1-0/+18
It seems the license header was omitted when dfp.m4 was originally contributed in 2010 (commit 3c39bca6bbb5, r0-102573 or svn r163815. This copies the license from libdecnumber/configure.ac since dfp.m4 was originally extracted from that file. 2022-04-29 Christophe Lyon <christophe.lyon@arm.com> config/ * dfp.m4: Add license header.

2021-11-30d: Import dmd b8384668f, druntime e6caaab9, phobos 5ab9ad256 (v2.098.0-beta.1)Iain Buclaw1-0/+12
The D front-end is now itself written in D, in order to build GDC, you will need a working GDC compiler (GCC version 9.1 or later). GCC changes: - Add support for bootstrapping the D front-end. These add the required components in order to have a D front-end written in D itself. Because the compiler front-end only depends on the core runtime modules, only libdruntime is built for the bootstrap stages. D front-end changes: - Import dmd v2.098.0-beta.1. Druntime changes: - Import druntime v2.098.0-beta.1. Phobos changes: - Import phobos v2.098.0-beta.1. The jump from v2.076.1 to v2.098.0 covers nearly 4 years worth of development on the D programming language and run-time libraries. ChangeLog: * Makefile.def: Add bootstrap to libbacktrace, libphobos, zlib, and libatomic. * Makefile.in: Regenerate. * Makefile.tpl (POSTSTAGE1_HOST_EXPORTS): Fix command for GDC. (STAGE1_CONFIGURE_FLAGS): Add --with-libphobos-druntime-only if target-libphobos-bootstrap. (STAGE2_CONFIGURE_FLAGS): Likewise. * configure: Regenerate. * configure.ac: Add support for bootstrapping D front-end. config/ChangeLog: * acx.m4 (ACX_PROG_GDC): New m4 function. gcc/ChangeLog: * Makefile.in (GDC): New variable.

2021-07-09Darwin, config: Revise host config fragment.Iain Sandoe1-24/+33
There were two uses for the Darwin host config fragment: The first is to arrange for targets that support mdynamic-no-pic to be built with that enabled (since it makes a significant difference to the compiler performance). We can be more specific in the application of this, since it only applies to 32b hosts plus powerpc64-darwin9. The second was to work around a tool bug where -fno-PIE was not propagated to the link stage. This second use is redundant, since the buggy toolchain cannot bootstrap current GCC sources anyway. This makes the host fragment more specific and reduces the number of toolchains for which it is included which reduces clutter in configure lines.

2021-01-05build: libcody: Link with -lsocket -lnsl if necessary [PR98316]Rainer Orth1-0/+40
With the introduction of C++20 modules and libcody, cc1plus and cc1objplus gained a dependency on the socket functions. Before those were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl on Solaris, so that merge broke the Solaris 11.3 build. While we already have 4 different checks for those libraries in the tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro instead. At the same time, the patch only links libcody and the networking libs where needed (cc1plus, cc1objplus). Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3 and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2020-12-16 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> c++tools: PR c++/98316 * configure.ac: Include ../config/ax_lib_socket_nsl.m4.

2020-11-25libsanitizer: mid-end: Introduce stack variable handling for HWASANMatthew Malcomson1-2/+6
Handling stack variables has three features. 1) Ensure HWASAN required alignment for stack variables When tagging shadow memory, we need to ensure that each tag granule is only used by one variable at a time. This is done by ensuring that each tagged variable is aligned to the tag granule representation size and also ensure that the end of each object is aligned to ensure the start of any other data stored on the stack is in a different granule. This patch ensures the above by forcing the stack pointer to be aligned before and after allocating any stack objects. Since we are forcing alignment we also use `align_local_variable` to ensure this new alignment is advertised properly through SET_DECL_ALIGN. 2) Put tags into each stack variable pointer Make sure that every pointer to a stack variable includes a tag of some sort on it. The way tagging works is: 1) For every new stack frame, a random tag is generated. 2) A base register is formed from the stack pointer value and this random tag. 3) References to stack variables are now formed with RTL describing an offset from this base in both tag and value. The random tag generation is handled by a backend hook. This hook decides whether to introduce a random tag or use the stack background based on the parameter hwasan-random-frame-tag. Using the stack background is necessary for testing and bootstrap. It is necessary during bootstrap to avoid breaking the `configure` test program for determining stack direction. Using the stack background means that every stack frame has the initial tag of zero and variables are tagged with incrementing tags from 1, which also makes debugging a bit easier. Backend hooks define the size of a tag, the layout of the HWASAN shadow memory, and handle emitting the code that inserts and extracts tags from a pointer. 3) For each stack variable, tag and untag the shadow stack on function prologue and epilogue. On entry to each function we tag the relevant shadow stack region for each stack variable. This stack region is tagged to match the tag added to each pointer to that variable. This is the first patch where we use the HWASAN shadow space, so we need to add in the libhwasan initialisation code that creates this shadow memory region into the binary we produce. This instrumentation is done in `compile_file`. When exiting a function we need to ensure the shadow stack for this function has no remaining tags. Without clearing the shadow stack area for this stack frame, later function calls could get false positives when those later function calls check untagged areas (such as parameters passed on the stack) against a shadow stack area with left-over tag. Hence we ensure that the entire stack frame is cleared on function exit. config/ChangeLog: * bootstrap-hwasan.mk: Disable random frame tags for stack-tagging during bootstrap. gcc/ChangeLog: * asan.c (struct hwasan_stack_var): New.

2020-11-25libsanitizer: Add option to bootstrap using HWASANMatthew Malcomson1-0/+8
This is an analogous option to --bootstrap-asan to configure. It allows bootstrapping GCC using HWASAN. For the same reasons as for ASAN we have to avoid using the HWASAN sanitizer when compiling libiberty and the lto-plugin. Also add a function to query whether -fsanitize=hwaddress has been passed. ChangeLog: * configure: Regenerate. * configure.ac: Add --bootstrap-hwasan option. config/ChangeLog: * bootstrap-hwasan.mk: New file. gcc/ChangeLog: * doc/install.texi: Document new option. libiberty/ChangeLog: * configure: Regenerate. * configure.ac: Avoid using sanitizer. lto-plugin/ChangeLog: * Makefile.am: Avoid using sanitizer. * Makefile.in: Regenerate.

It has already been approved and installed for binutils-gdb in the thread starting at [PATCH] Unify Solaris procfs and largefile handling https://sourceware.org/pipermail/gdb-patches/2020-June/169977.html I'm syncing the config/largefile.m4 part to gcc now which is the master for config.
