`./configure` doesn't allow setting hashmap toml values

[jyn514]

I tried this code:

./configure --set llvm.build-config.LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=YES

I expected to see this happen: configure.py generates a toml file with the contents

build-config = {"LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN"="YES"}

Instead, this happened:

; ./configure --set llvm.build-config.LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=YES
configure: processing command line
configure: 
configure: llvm.build-config.LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN := YES
configure: build.configure-args := ['--set', 'llvm.build-config.LLVM_TEMPORARILY_ ...

I have a PR ready but I need to wait for #108618 to get merged since that PR was master -> master and creating a new branch now doesn't help 😔

You can run git checkout upstream/master (replace upstream with the name of the rust-lang remote), then run git switch -c <new branch name>.
In the future, take the habit of always having your master branch fast-forward able, it will avoid you hassles with the GitHub UI.

That worked for me, Thank you so much!
