2019-11-18musl: Don't use gthr weak refs in libgcc PR91737Szabolcs Nagy1-0/+2
The gthr weak reference based single thread detection is unsafe with static linking and in case of dynamic linking it's ineffective on musl since pthread symbols are defined in libc.so. (Ideally this should be fixed for all targets, since glibc plans to move libpthread.so into libc.so too and users want to static link to pthread without --whole-archive: PR87189.) For now we have to explicitly opt out from the broken behaviour in the config machinery of each target lib and libgcc was previously missed. libgcc/ChangeLog: 2019-11-18 Szabolcs Nagy <szabolcs.nagy@arm.com> * config.host: Add t-gthr-noweak on *-*-musl*. * config/t-gthr-noweak: New file.

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.

2019-07-31[Arm][CMSE]Add warn_unused_return attribute to cmse functionsJoel Hutton1-0/+1
At present it is possible to call the CMSE functions for checking addresses (such as cmse_check_address_range) and forget to check/use the return value. This patch makes the interfaces more robust against programmer error by marking these functions with the warn_unused_result attribute. With this set, any use of these functions that does not use the result will produce a warning. This produces a warning on default warn levels when the result of the cmse functions is not used. For the following function: void foo() { int *data; cmse_check_address_range((int*)data, 0, 0); } The following warning is emitted: warning: ignoring return value of 'cmse_check_address_range' declared with attribute 'warn_unused_result' [-Wunused-result] 6 | cmse_check_address_range((int*)data, 0, 0); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcc/ChangeLog: 2019-07-31 Joel Hutton <Joel.Hutton@arm.com> * config/arm/arm_cmse.h (cmse_nonsecure_caller): Add warn_unused_result attribute.

2019-06-06Darwin, PowerPC, libgcc - Ensure unwinder is built with altivec enabled.Iain Sandoe1-0/+3
When libgcc is built on Darwin, it is usually built for the earliest potential target (Darwin8, 10.4). Build for that revision default to assuming that the processor might be G3 (without vector ops) and there is an outlined function used for save/restore that checks whether the processor is G3 or G4+ at run- time. However, the unwinder itself needs to be built with the assumption of vector usage so that the relevant outlined functions are called. 2019-06-06 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/t-darwin: Ensure that the unwinder is built with altivec enabled.
