2017-07-20Replace 'struct ucontext' with 'ucontext_t' typeKhem Raj1-2/+2
glibc used to have: typedef struct ucontext { ... } ucontext_t; glibc now has: typedef struct ucontext_t { ... } ucontext_t; (See https://sourceware.org/bugzilla/show_bug.cgi?id=21457 for detail and rationale for the glibc change) However, QEMU used "struct ucontext" in declarations. This is a private name and compatibility cannot be guaranteed. Switch to only using the standardized type name.

2017-07-11tests: Avoid non-portable 'echo -ARG'Eric Blake1-4/+4
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.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-1/+1
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2014-05-07tests/tcg: Fix compilation of test_pathPeter Maydell2-9/+0
The test_path binary is (unlike the other test binaries in tests/tcg) actually intended to be compiled with the same compiler used to build the main QEMU executables. It actually #includes a number of the QEMU source files in an attempt to unit-test the util/path.c functions, and so if it is not compiled with the same compiler used by configure to set CONFIG_ settings then it is liable to fail to build. Fix the makefile to build it with the default C compiler rules, not CC_I386, and fix the test itself not to include a lot of unnecessary trace related source files which cause the build to fail if the trace backend is anything other than 'simple'.
