[PATCH] [arm] require armv7 support for [PR120424] (was: Re: [PATCH, FYI?] [arm] [vxworks] require thumb2 for pr120424.C)

It turned out that the regression report I got from linaro was related https://linaro.atlassian.net/browse/GNU-1599 While testing a configuration with -mfloat-abi=hard, -marmv7 is rejected because it doesn't have an FPU. Requiring thumb2 wouldn't have avoided this failure, but requiring armv7 is a proper fix for both problems. (sorry it me took so long; I'm still busy busy with other fp2sp-elimination-disabled-during-lra problems affecting arm) Without stating the architecture version required by the test, test runs with options that are incompatible with the required architecture version fail, e.g. -mfloat-abi=hard. armv7 was not covered by the long list of arm variants in target-supports.exp, so add it, and use it for the effective target requirement and for the option. Tested on arm-eabi, and also on arm-vx7r2 with gcc-14.

How can I reproduce a flang-arm64-windows-msvc LLVM buildbot error?

by tobias.gysi＠nextsilicon.com

Dear Linaro Community, I am looking for advice on how to reproduce a flang-arm64-windows-msvc LLVM build bot failure (hopefully I ended up in the right place here). I had to revert an LLVM PR (https://github.com/llvm/llvm-project/pull/150783) that broke the flang-arm64-windows-msvc LLVM buildbot yesterday due to some tablegen-related problem. I did prepare a reland PR (https://github.com/llvm/llvm-project/pull/151125) that addresses a potential issue. However, since I did not see any other buildbot failures and since I was not able to reproduce the problem locally, I wonder if there is a way to run the flang-arm64-windows-msvc buildbot on my reland PR? Alternatively, hints on how to reproduce the problem locally on a x86 Linux machine would be appreciated. Best, Tobias
