-qemu-x86_64: qemu/tcg/ppc/tcg-target.c.inc:1777:tcg_out_test: code should not be reached
-Description of problem:
-Using this basic test file:
-
-```c
-int
-main (void)
-{
-    return 0;
-}
-```
-
-compiled into a static executable using an x86_64 toolchain (glibc or musl both tested),
-
-```
-gwyn ~/qemu-bug # file test1
-test1: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), static-pie linked, with debug_info, not stripped
-
-gwyn ~/qemu-bug # file test2
-test2: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, BuildID[sha1]=276dc49ee7cbd3b760e24761bf9fb9e1cc4b4349, for GNU/Linux 3.2.0, not stripped
-```
-
-Using QEMU from 15957eb9efe2da67c796612cead95cba28ba9bda or newer:
-
-```
-gwyn ~/qemu-bug # ../emus-ppc64/bin/qemu-x86_64 --version
-qemu-x86_64 version 9.0.50 (v9.0.0-521-g15957eb9ef-dirty)
-Copyright (c) 2003-2024 Fabrice Bellard and the QEMU Project developers
-```
-
-QEMU crashes:
-
-```
-gwyn ~/qemu-bug # ../emus-ppc64/bin/qemu-x86_64 ./test2
-**
-ERROR:/root/qemu/tcg/ppc/tcg-target.c.inc:1777:tcg_out_test: code should not be reached
-Bail out! ERROR:/root/qemu/tcg/ppc/tcg-target.c.inc:1777:tcg_out_test: code should not be reached
-Aborted
-```
-Steps to reproduce:
-1. Build QEMU user for ppc64 (may affect other hosts) using commit 15957eb9efe2da67c796612cead95cba28ba9bda or newer.
-2. Run any simple x86_64 executable.
-3. Observe the crash.

-    target/i386: use TSTEQ/TSTNE to test low bits
-    
-    When testing the sign bit or equality to zero of a partial register, it
-    is useful to use a single TSTEQ or TSTNE operation.  It can also be used
-    to test the parity flag, using bit 0 of the population count.
-    
-    Do not do this for target_ulong-sized values however; the optimizer would
-    produce a comparison against zero anyway, and it avoids shifts by 64
-    which are undefined behavior.
