Fix llvm-libunwind userspace build on ARM GCC's libgcc exports a few ARM-specific symbols for ARM EABI, AEABI, or EHABI or whatever it's called. Export the same ones from LLVM-libunwind's libgcc_s, on ARM. As part of this, convert libgcc_s from a direct Version.map to one constructed from component Symbol.map files. This allows the ARM-specific Symbol.map to be included only on ARM. Fix ARM-only oddities in struct name/aliases in LLVM-libunwind to match non-ARM definitions and ARM-specific expectations in libcxxrt / libcompiler_rt. No functional change intended for non-ARM architectures. This commit does not actually flip the switch for ARM defaults from libgcc to llvm-libunwind, but makes it possible (to compile, anyway). 2019-11-05 03:20:40 +00:00			`/*`

Export _Unwind_Complete and _Unwind_VRS_Pop from arm's libgcc_s Apparently some ports on arm require these symbols, and while they were available in llvm's libunwind, they were never exported via the arm specific Symbol.map. Put them in the same version block as gcc does (GCC_3.5). Reported by: Robert Clausecker <fuz_at_fuz.su> MFC after: 3 days 2022-04-27 09:04:10 +00:00			`_Unwind_Complete;`

Fix LLVM libunwnwind _Unwind_Backtrace symbol version for ARM. In original GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version for all architectures but ARM. For ARM should be publishes with GCC_4.3.0 version. This was originally omitted in r255095, fixed in r318024 and omitted aging in LLVM libunwind implementation in r354347. For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0 version , (because this is right original version) and again as normal(not-default) with GCC_3.3 version (to maintain ABI compatibility compiled/linked with wrong pre r318024 libgcc) PR: 233664 2019-12-16 14:08:49 +00:00
