POSIX says that backslashes in the arguments to 'echo', as well as any use of 'echo -n' and 'echo -e', are non-portable; it recommends people should favor 'printf' instead. This is definitely true where we do not control which shell is running (such as in makefile snippets or in documentation examples). But even for scripts where we require bash (and therefore, where echo does what we want by default), it is still possible to use 'shopt -s xpg_echo' to change bash's behavior of echo. And setting a good example never hurts when we are not sure if a snippet will be copied from a bash-only script to a general shell script (although I don't change the use of non-portable \e for ESC when we know the running shell is bash). Replace 'echo -n "..."' with 'printf %s "..."', and 'echo -e "..."' with 'printf %b "...\n"', with the optimization that the %s/%b argument can be omitted if the string being printed is a strict literal with no '%', '$', or '`' (we could technically also make this optimization when there are $ or `` substitutions but where we can prove their results will not be problematic, but proving that such substitutions are safe makes the patch less trivial compared to just being consistent). In the qemu-iotests check script, fix unusual shell quoting that would result in word-splitting if 'date' outputs a space. In test 051, take an opportunity to shorten the line. In test 068, get rid of a pointless second invocation of bash.

This directory contains various interesting programs for regression testing. The target "make test" runs the programs and, if applicable, runs "diff" to detect mismatches between output on the host and output on QEMU. i386 ==== test-i386 --------- This program executes most of the 16 bit and 32 bit x86 instructions and generates a text output, for comparison with the output obtained with a real CPU or another emulator. The Linux system call modify_ldt() is used to create x86 selectors to test some 16 bit addressing and 32 bit with segmentation cases. The Linux system call vm86() is used to test vm86 emulation. Various exceptions are raised to test most of the x86 user space exception reporting. linux-test ---------- This program tests various Linux system calls. It is used to verify that the system call parameters are correctly converted between target and host CPUs. test-i386-fprem --------------- runcom ------ test-mmap --------- sha1 ---- hello-i386 ---------- ARM === hello-arm --------- test-arm-iwmmxt --------------- MIPS ==== hello-mips ---------- hello-mipsel ------------ CRIS ==== The testsuite for CRIS is in tests/tcg/cris. You can run it with "make test-cris". LM32 ==== The testsuite for LM32 is in tests/tcg/cris. You can run it with "make test-lm32".
