In the meantime, I am puzzled by your statement that there is no testsuite coverage for VTV: VTV does indeed have a small testsuite. It is in the libvtv directory, because it makes no sense (and the tests all fail) if you try to run it when VTV is not enabled. But if you shift to the libvtv build tree and try make check you should see the VTV tests run.

Backport from trunk Enable C++ exceptions and RTTI by default. Modify LINK_SPEC to pass --fix-cortex-a53-843419 as default Rename libstdc++.so to libgnustl_shared.so when enabling bionic libs. Drop mips64r2 from Android compiler's multilib Merge "Drop mips64r2 from Android compiler's multilib" Adjust several costs for AArch64: Refactor aarch64_address_costs; add cost tables for Cortex-A7; better estimate cost of building a constant; wrap aarch64_rtx_costs to dump verbose output; factor out common MULT cases; det default costs and handle vector modes; cost memory accesses using address costs; better cost logical operations; improve costs for div/mod and sign/zero extend operations; cost comparisons, flag setting operators and IF_THEN_ELSE; cost more Floating point RTX; cost TRUNCATE, SET, SYMBOL_REF, HIGH and LO_SUM; dump a message if we are unable to cost an insn; fix typos in cost data structure. Add several improvements for AArch64 (Backported from GCC 5): (spill code - swap order in shr patterns; spill code - swap order in shl pattern; fix aarch64_rtx_costs of PLUS/MINUS; cost operand 0 in FP compare-with-0.0 case; properly cost FABD pattern; properly handle mvn-register and add EON+shift pattern and cost appropriately).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59507 ctice at gcc dot gnu.org changed: What|Removed |Added CC||ctice at gcc dot gnu.org --- Comment #3 from ctice at gcc dot gnu.org --- This is caused by the verification call being inserted after an exception handler landing pad, in the same basic block as the landing pad, when GCC expects the landing pad statement to be the last statement in the basic block. The fix for this will be to split all the outgoing edges and insert new basic blocks on each, with the verification call in there instead. I will work on this, but it may take me a little time to get right.

[Bug other/101711] Error when gcc cross compile libvtv
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101711 --- Comment #10 from ctice at gcc dot gnu.org --- I have been trying off-and-on for the last 3 weeks to build a ming64 GCC cross-compiler, on my x86_64 linux ELF system, and I have not been able to do it. This is without enabling libvtv. The instructions referenced on https://sourceforge.net/p/mingw-w64/wiki2/Cross%20Win32%20and%20Win64%20compiler/ are at least 8 years out of date, and I have not been able to make them work. Until I can get a set of instructions that works, I cannot reproduce the problem, and without reproducing it I cannot debug/fix it. I am sorry about this, but I really have tried.

I'm getting configure/build failures even when I omit enabling vtable verify; I also don't know where/how to get the mcf thread libraries? [Instructions for both of these are necessary if I am to debug the libvtv issue].

[Bug other/101711] Error when gcc cross compile libvtv
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101711 --- Comment #6 from ctice at gcc dot gnu.org --- I applied the patch supplied in comment 5. I added --with-sysroot=/usr/local to my configure command (still not using --enable-threads=mcf or --enable-vtable-verify). Now it configures, but the make command fails while building gcc, complaining that: The directory that should contain system headers does not exist: /usr/local/mingw/include Which is completely true. I'm working on an elf/linux machine (x86_64) and I have no mingw headers. Where can I get the appropriate headers (and anything else I will need) in order to make this cross compile work?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101711 --- Comment #7 from ctice at gcc dot gnu.org --- Also, I downloaded the sources for mcfgthread from the repo supplied in comment5, but I can't seem to get that to build -- the GCC on my machine does not recognize "-municode" as a valid flag. Is there something else I need in order to be able to build the library?
