From b7f47e82e2d8ccf368d70fc4fd1467db55a74a32 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 30 Sep 2020 13:13:52 +0200 Subject: [PATCH] tests/qtest/libqtest: Fix detection of architecture for binaries without path The qtests can be run directly by specifying the QEMU binary with the QTEST_QEMU_BINARY environment variable, for example: $ QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/qtest/test-hmp However, if you specify a binary without a path, for example with QTEST_QEMU_BINARY=qemu-system-x86_64 if the QEMU binary is in your $PATH, then the test currently simply crashes. Let's try a little bit smarter here by looking for the final '-' instead of the slash.
