2013-06-24Fix host_name and target_name generation by common/create-version.sh.Joel Brobecker1-2/+2
This new script has one small snafoo, which prevented the $host_alias and $target_alias from being expanded during the generation of the version.c file. As a result, the version info yields: This GDB was configured as "--host=$host_alias --target=$target_alias". ^^^^^^^^^^^ ^^^^^^^^^^^^^ This patch fixes this issue. gdb/ChangeLog: * common/create-version.sh: Fix expansion of $host_alias and $target_alias in generation of HOST_NAME and TARGET_NAME (resp.).
2013-06-24don't keep a gdb-specific dateTom Tromey3-0/+70
Right now there are two nightly commits to update a file in the tree with the current date. One commit is for BFD, one is for gdb. It seems unnecessary to me to do this twice. We can make do with a single such commit. This patch changes gdb in a minimal way to reuse the BFD date -- it extracts it from bfd/version.h and changes version.in to use the placeholder string "DATE" for those times when a date is wanted. I propose removing the cron job that updates the version on trunk, and then check in this patch. For release branches, we can keep the cron job, but just tell it to rewrite bfd/version.h. I believe this is a simple change in the crontab -- the script will work just fine on this file. This also moves version.in and version.h into common/, to reflect their shared status; and updates gdbserver to use version.h besides. * common/create-version.sh: New file. * Makefile.in (version.c): Use bfd/version.h, common/version.in, create-version.sh.

2013-06-19gdb: clean up x86 cpuid implementationsMike Frysinger3-31/+345
We've currently got 3 files doing open coded implementations of cpuid. Each has its own set of workarounds and varying levels of how well they're written and are generally hardcoded to specific cpuid functions. If you try to build the latest gdb as a PIE on an i386 system, the build will fail because one of them lacks PIC workarounds (wrt ebx). Specifically, we have: common/linux-btrace.c: two copies of cpuid asm w/specific args, one has no workarounds while the other implicitly does to avoid memcpy go32-nat.c: two copies of cpuid asm w/specific args, one has workarounds to avoid memcpy gdb/testsuite/gdb.arch/i386-cpuid.h: one general cpuid asm w/many workarounds copied from older gcc Fortunately, that last header there is pretty damn good -- it handles lots of edge cases, the code is nice & tight (uses gcc asm operands rather than manual movs), and is already almost a general library type header. It's also the basis of what is now the public cpuid.h that is shipped with gcc-4.3+. So what I've done is pull that test header out and into gdb/common/ (not sure if there's a better place), synced to the version found in gcc-4.8.0, put a wrapper API around it, and then cut over all the existing call points to this new header. Since the func already has support for "is cpuid supported on this proc", it makes it trivial to push the i386/x86_64 ifdefs down into this wrapper API too. Now it can be safely used for all targets and gcc will elide the unused code for us. I've verified the gdb.arch testsuite still passes, and this code compiles for an armv7a host as well as x86_64. The go32-nat code has been left ifdef-ed out until someone can test & verify the new stuff works (and if it doesn't, figure out how to make the new code work).
