2018-05-16[OR1K] Add the EPCR special-purpose register to register state.whitequark
This makes it possible to unwind hardware exception stack frames, which necessarily save every register and so need an extra column for storing the return address. CFI for the exception handler could then look as follows: .globl exception_vector exception_vector: .cfi_startproc .cfi_signal_frame .cfi_return_column 32 l.addi r1, r1, -0x100 .cfi_def_cfa_offset 0x100 l.sw 0x00(r1), r2 .cfi_offset 2, 0x00-0x100 l.sw 0x04(r1), r3 .cfi_offset 3, 0x04-0x100 l.sw 0x08(r1), r4 .cfi_offset 4, 0x08-0x100 l.mfspr r3, r0, SPR_EPCR_BASE l.sw 0x78(r1), r3 .cfi_offset 32, 0x78-0x100 l.jal exception_handler l.nop l.lwz r2, 0x00(r1) l.lwz r3, 0x04(r1) l.lwz r4, 0x08(r1) l.jr r9 l.nop .cfi_endproc This register could, of course, also be accessed by the trace callback or personality function, if so desired. git-svn-id: https://llvm.org/svn/llvm-project/libunwind/trunk@332513 91177308-0d34-0410-b5e6-96231b3b80d8
2018-05-16[OR1K] Add a dedicated PC register to register state.whitequark
Before this commit, R9, the link register, was used as PC register. However, a stack frame may have R9 not set to PC on entry, either because it uses a custom calling convention, or, more likely, because this is a signal or exception stack frame. Using R9 as PC register made it impossible to unwind such frames. All other architectures similarly use a dedicated PC register. git-svn-id: https://llvm.org/svn/llvm-project/libunwind/trunk@332512 91177308-0d34-0410-b5e6-96231b3b80d8
2018-05-15[libunwind][MIPS] Support MIPS floating-point registers for hard-float ABIs.John Baldwin
Summary: For MIPS ABIs with 64-bit floating point registers including newabi and O32 with 64-bit floating point registers, just save and restore the 32 floating-point registers as doubles. For O32 MIPS with 32-bit floating-point registers, save and restore the individual floating-point registers as "plain" registers. These registers are encoded as floats rather than doubles, but the DWARF unwinder assumes that floating-point registers are stored as doubles when reading them from memory (via AddressSpace::getDouble()). Treating the registers as "normal" registers instead causes the DWARF unwinder to fetch them from memory as a 32-bit register. This does mean that for O32 with 32-bit floating-point registers unw_get_fpreg() and unw_set_fpreg() do not work. One would have to use unw_get_reg() and unw_set_reg() instead. However, DWARF unwinding works correctly as the DWARF CFI emits records for individual 32-bit floating-point registers even when they are treated as doubles stored in paired registers. If the lack of unw_get/set_fpreg() becomes a pressing need in the future for O32 MIPS we could add in special handling to make it work.

2018-02-27[libunwind][MIPS]: Add support for unwinding in N32 processes.John Baldwin
Summary: N32 uses the same register context as N64. However, N32 requires one change to properly fetch addresses from registers stored in memory. Since N32 is an ILP32 platform, getP() only fetches the first 32-bits of a stored register. For a big-endian platform this fetches the upper 32-bits which will be zero. To fix this, add a new getRegister() method to AddressSpace which is responsible for extracting the address stored in a register in memory. This matches getP() for all current ABIs except for N32 where it reads the 64-bit register and returns the low 32-bits as an address. The DwarfInstructions::getSavedRegister() method uses AddressSpace::getRegister() instead of AddressSpace::getP().

2017-12-25[libunwind] Add proper support for DWARF unwind on bare metal.whitequark
Right now, ARM EHABI unwind on bare metal expects to find the symbols __exidx_start and __exidx_end defined, and uses those to locate the EH tables. However, DWARF unwind on bare metal expects to find dl_iterate_phdr, which, although possible to provide, is inconvenient and mildly absurd. This commit provides feature parity with ARM EHABI unwind by looking for symbols __eh_frame_start, __eh_frame_end, __eh_frame_hdr_start and __eh_frame_hdr_end, denoting the start and end of the sections with corresponding names. As far as I know, there is no de jure or de facto ABI providing any such names, so I chose the obvious ones. The .eh_frame_hdr support is optional for maximum flexibility and possible space savings (e.g. if libunwind is only used to provide backtraces when a device crashes, providing the .eh_frame_hdr, which is an index for rapid access to EH tables, would be a waste.) The support for .eh_frame_hdr/DWARF index in the first place is conditional on defined(_LIBUNWIND_SUPPORT_DWARF_INDEX), although right now config.h will always define this macro. The support for DWARF unwind on bare metal has been validated within the ARTIQ environment[1].

2017-12-25[libunwind] convert error logs to _LIBUNWIND_LOG/_LIBUNWIND_LOG0.whitequark
Use the `_LIBUNWIND_LOG` and `_LIBUNWIND_LOG0` macros instead of the explicit `fprintf` call. This was previously done in r292721 as a cleanup and then reverted in r293257 because the implementation in r292721 relied on a GNU extension. This implementation avoids the use of an extension by using a second macro instead, and allows to avoid the dependency on fprintf if _LIBUNWIND_BARE_METAL is defined. git-svn-id: https://llvm.org/svn/llvm-project/libunwind/trunk@321441 91177308-0d34-0410-b5e6-96231b3b80d8
