説明

The following tests fail with a mesage like this on a debug win64 test job:

Unhandled Exception: System.BadImageFormatException: 
Could not load file or assembly '<testname>.exe' or one of its dependencies.
An attempt was made to load a program with an incorrect format.

The failing tests are:

JIT\Directed\tls\mutualrecurthd-tls\mutualrecurthd-tls.cmd
JIT\Directed\tls\test-tls\test-tls.cmd
JIT\Regression\CLR-x86-EJIT\v1-m10\b07847\b07847\b07847.cmd
JIT\Regression\CLR-x86-JIT\V1.2-M01\b03689\b03689\b03689.cmd

調査方針: Investigate the test configuration for debug win64 builds. The BadImageFormatException suggests a mismatch between the test assembly platform and the runtime. Review the test files (e.g., JIT/Directed/tls/mutualrecurthd tls/mutualrecurthd tls.cmd) to ensure they are built for x64. Check the build scripts for these tests to confirm the platform target. Also, examine any recent changes to the test infrastructure that might have introduced this issue.
