LNK1223 error when building rustc with custom LLVM under windows

[Escapingbug]

I am currently trying to experiment with a llvm patch under windows, and needing a way to build rustc with that patched LLVM.
What I am tring is:

1. build my own llvm, install that to some dir, command:

cmake -G "Ninja" ../llvm -DCMAKE_INSTALL_PREFIX=~/myllvm -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;lld;" -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_INSTALL_UTILS=ON -DLLVM_INCLUDE_TESTS=OFF -DLLVM_BUILD_TESTS=OFF -DLLVM_INCLUDE_BENCHMARKS=OFF -DLLVM_BUILD_BENCHMARKS=OFF 

2. clone the rustc repo, copy the config.example.toml to config.toml, and change:

• set debug to false
• target from target.x86_64-unknown-linux-gnu to target.x86_64-pc-windows
• uncomment llvm-config and set that to my installed llvm's llvm-config
• change the channel from "dev" to "nightly"

3. python3 x.py build

The next thing I encounter is something like in this issue.

The author mentioned a possible workaround by crt-static=true and LLVM_USE_CRT sets to MT.
So I did that and set LLVM_USE_CRT_RELEASE to MT (also, LLVM is built under release) by adding -DLLVM_USE_CRT_RELEASE=MT, and build again.

Then I got this problem:

It says the file contains invalid .pdata base value.

Nevermind, it seems to be related to my patch.
