2020-03-26arm: unified syntax for libgcc when built with -Os [PR94220]Richard Earnshaw1-16/+17
The recent patch to convert all thumb1 code in libgcc to unified syntax ommitted the conditional code that is used only when building the library for minimal size. This patch fixes this case. I've also fixed the COND macro so that a single definition is always used that is for unified syntax. This eliminates a warning that is now being seen from the assembler when compiling the ieee fp support code.

2020-03-03libgcc: arm: convert thumb1 code to unified syntaxRichard Earnshaw3-277/+296
Unified syntax has been the official syntax for thumb1 assembly for over 10 years now. It's time we made preparations for that becoming the default in the assembler. But before we can start doing that we really need to clean up some laggards from the olden days. Libgcc support for thumb1 is one such example. This patch converts all of the legacy (disjoint) syntax that I could find over to unified code. The identification was done by using a trick version of gas that defaulted to unified mode which then faults if legacy syntax is encountered. The code produced was then compared against the old code to check for differences. One such difference does exist, but that is because in unified syntax 'movs rd, rn' is encoded as 'lsls rd, rn, #0', rather than 'adds rd, rn, #0'; but that is a deliberate change that was introduced because the lsls encoding more closely reflects the behaviour of 'movs' in arm state (where only some of the condition flags are modified). * config/arm/bpabi-v6m.S (aeabi_lcmp): Convert thumb1 code to unified syntax.

2020-02-10i386: Properly pop restore token in signal frameH.J. Lu1-0/+43
Linux CET kernel places a restore token on shadow stack for signal handler to enhance security. The restore token is 8 byte and aligned to 8 bytes. It is usually transparent to user programs since kernel will pop the restore token when signal handler returns. But when an exception is thrown from a signal handler, now we need to pop the restore token from shadow stack. For x86-64, we just need to treat the signal frame as normal frame. For i386, we need to search for the restore token to check if the original shadow stack is 8 byte aligned. If the original shadow stack is 8 byte aligned, we just need to pop 2 slots, one restore token, from shadow stack. Otherwise, we need to pop 3 slots, one restore token + 4 byte padding, from shadow stack. This patch also includes 2 tests, one has a restore token with 4 byte padding and one without. Tested on Linux/x86-64 CET machine with and without -m32. libgcc/ PR libgcc/85334 * config/i386/shadow-stack-unwind.h (_Unwind_Frames_Increment): New. gcc/testsuite/ PR libgcc/85334 * g++.target/i386/pr85334-1.C: New test. * g++.target/i386/pr85334-2.C: Likewise.
2020-02-07arm: Fix up arm installed unwind.h for use in pedantic modes [PR93615]Jakub Jelinek1-9/+5
As the following testcase shows, unwind.h on ARM can't be (starting with GCC 10) compiled with -std=c* modes, only -std=gnu* modes. The problem is it uses asm keyword, which isn't a keyword in those modes (system headers vs. non-system ones don't make a difference here). glibc and other installed headers use __asm or __asm__ keywords instead that work fine in both standard and gnu modes. While there, as it is an installed header, I think it is also wrong to completely ignore any identifier namespace rules. The generic unwind.h defines just _Unwind* namespace identifiers plus _sleb128_t/_uleb128_t (but e.g. unlike libstdc++/glibc headers doesn't uglify operand names), the ARM unwind.h is much worse here. I've just changed the gnu_Unwind_Find_got function at least not be in user identifier namespace, but perhaps it would be good to go further and rename e.g. or e.g. typedef _Unwind_Reason_Code (*personality_routine) (_Unwind_State, _Unwind_Control_Block *, _Unwind_Context *); in unwind-arm-common.h. 2020-02-07 Jakub Jelinek <jakub@redhat.com> PR target/93615 * config/arm/unwind-arm.h (gnu_Unwind_Find_got): Rename to ...

2020-01-31nios2: Support for GOT-relative DW_EH_PE_datarel encoding.Sandra Loosemore1-0/+24
On nios2-linux-gnu, there has been a long-standing bug in C++ exception handling that sometimes resulted in link errors like ../nios2-linux-gnu/bin/ld: FDE encoding in /tmp/cccfpQ2l.o(.eh_frame) prevents .eh_frame_hdr table being created when building some shared libraries or PIE executables. The root of the problem is that GCC was incorrectly emitting an absolute encoding in EH tables for PIC. This patch changes it to use either DW_EH_PE_indirect (for global) or DW_EH_PE_datarel (for local), and fixes libgcc so it can find the address of the GOT as the base address for DW_EH_PE_datarel. Complicating matters somewhat, GAS was missing support for %gotoff(symbol) relocation syntax. I have just pushed a fix for that, but I've added a configure check to test for presence of the binutils support and fall back to the current absolute encoding (which works most of the time) if it is not available. Once the fix makes it into an official binutils release it might be appropriate to make this error out instead. Since this is a wrong-code bug and affects only nios2 target, I think this is appropriate for Stage 4. I regression-tested on both nios2-linux-gnu and nios2-elf, with and without the binutils support present, before committing this. 2020-01-31 Sandra Loosemore <sandra@codesourcery.com> gcc/ * configure.ac [nios2-*-*]: Check HAVE_AS_NIOS2_GOTOFF_RELOCATION. * config.in: Regenerated. * configure: Regenerated. * config/nios2/nios2.h (ASM_PREFERRED_EH_DATA_FORMAT): Fix handling for PIC when HAVE_AS_NIOS2_GOTOFF_RELOCATION.

2020-01-27[ARC] Make libgcc compatible with ARC's reduced register set config.Claudiu Zissulescu7-17/+120
ARC processors can work with a reduced register set (i.e. registers r4-r9 and r16-r25 are not available). This option can be enabled passing -mrf16 option to the compiler, or by using -mcpu=em_mini CPU configuration. Using RF16 config requires all the hand-made assembly files used in libgcc to have the corresponding RF16 object attribute set. This patch qualifies the relevant hand-made assembly files to RF16 config, and also adds generic c-functions for the one which are not. libgcc/ xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com> * config/arc/crti.S: Add RF16 object attribute. * config/arc/crtn.S: Likewise. * config/arc/crttls.S: Likewise. * config/arc/lib1funcs.S: Likewise. * config/arc/fp-hack.h (ARC_OPTFPE): Define. * config/arc/lib2funcs.c: New file. * config/arc/t-arc: Add lib2funcs to LIB2ADD.

Without this, when we are unwinding across a signal frame we can jump to an even address which leads to an exception. This is needed in __gnu_persnality_sigframe_fdpic() when restoring the PC from the signal frame since the PC saved by the kernel has the LSB bit set to zero. 2019-09-10 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> libgcc/ * config/arm/unwind-arm.c (_Unwind_VRS_Set): Handle thumb-only architecture.

2019-09-10[ARM/FDPIC v6 06/24] [ARM] FDPIC: Add support for c++ exceptionsChristophe Lyon2-3/+83
The main difference with existing support is that function addresses are function descriptor addresses instead. This means that all code dealing with function pointers now has to cope with function descriptors instead. For the same reason, Linux kernel helpers can no longer be called by dereferencing their address, so we implement wrappers that directly call the kernel helpers. When restoring a function address, we also have to restore the FDPIC register value (r9). 2019-09-10 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> gcc/ * ginclude/unwind-arm-common.h (unwinder_cache): Add reserved5 field. libgcc/ * config/arm/linux-atomic.c (__kernel_cmpxchg): Add FDPIC support.

2019-09-09GCC port for eBPFJose E. Marchesi3-0/+23
This patch series introduces a port of GCC to eBPF, which is a virtual machine that resides in the Linux kernel. Initially intended for user-level packet capture and filtering, eBPF is nowadays generalized to serve as a general-purpose infrastructure also for non-networking purposes. The binutils support is already upstream. See https://sourceware.org/ml/binutils/2019-05/msg00306.html. ChangeLog: * MAINTAINERS: Add myself as the maintainer of the eBPF port. Remove myself from Write After Approval section. * configure.ac: Support for bpf-*-* targets. * configure: Regenerate. contrib/ChangeLog: * config-list.mk (LIST): Disable go in bpf-*-* targets. gcc/ChangeLog: * doc/invoke.texi (Option Summary): Cover eBPF.
