2023-07-11libgcc: Fix -Wint-conversion warning in find_fde_tailFlorian Weimer1-1/+1
Fixes commit r14-1614-g49310a99330849 ("libgcc: Fix eh_frame fast path in find_fde_tail"). libgcc/ PR libgcc/110179 * unwind-dw2-fde-dip.c (find_fde_tail): Add cast to avoid implicit conversion of pointer value to integer.
2023-06-07libgcc: Fix eh_frame fast path in find_fde_tailFlorian Weimer1-1/+1
The eh_frame value is only used by linear_search_fdes, not the binary search directly in find_fde_tail, so the bug is not immediately apparent with most programs. Fixes commit e724b0480bfa5ec04f39be8c7290330b495c59de ("libgcc: Special-case BFD ld unwind table encodings in find_fde_tail"). libgcc/ PR libgcc/109712 * unwind-dw2-fde-dip.c (find_fde_tail): Correct fast path for parsing eh_frame.

2022-11-04libgcc: Special-case BFD ld unwind table encodings in find_fde_tailFlorian Weimer1-10/+48
BFD ld (and the other linkers) only produce one encoding of these values. It is not necessary to use the general read_encoded_value_with_base decoding routine. This avoids the data-dependent branches in its implementation. libgcc/ * unwind-dw2-fde-dip.c (find_fde_tail): Special-case encoding values actually used by BFD ld.
2022-02-25libgcc: fix a warning calling find_fde_tailXi Ruoyao1-1/+1

2021-11-25libgcc: Split FDE search code from PT_GNU_EH_FRAME lookupFlorian Weimer1-42/+50
This allows switching to a different implementation for PT_GNU_EH_FRAME lookup in a subsequent commit. This moves some of the PT_GNU_EH_FRAME parsing out of the glibc loader lock that is implied by dl_iterate_phdr. However, the FDE is already parsed outside the lock before this change, so this does not introduce additional crashes in case of a concurrent dlclose. libgcc/ChangeLog: * unwind-dw2-fde-dip.c (struct unw_eh_callback_data): Add hdr. Remove func, ret. (find_fde_tail): New function. Split from _Unwind_IteratePhdrCallback. Move the result initialization from _Unwind_Find_FDE. (_Unwind_Find_FDE): Updated to call find_fde_tail.

2020-01-31nios2: Support for GOT-relative DW_EH_PE_datarel encoding.Sandra Loosemore1-1/+1
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.
