| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 307538: Move mksubr from kdump into libsysdecode. Restructure this script so that it generates a header of tables instead of a source file. The tables are included in a flags.c source file which provides functions to decode various system call arguments. For functions that decode an enumeration, the function returns a pointer to a string for known values and NULL for unknown values. For functions that do more complex decoding (typically of a bitmask), the function accepts a pointer to a FILE object (open_memstream() can be used as a string builder) to which decoded values are written. If the function operates on a bitmask, the function returns true if any bits were decoded or false if the entire value was valid. Additionally, the third argument accepts a pointer to a value to which any undecoded bits are stored. This pointer can be NULL if the caller doesn't care about remaining bits. Convert kdump over to using decoder functions from libsysdecode instead of mksubr. truss also uses decoders from libsysdecode instead of private lookup tables, though lookup tables for objects not decoded by kdump remain in truss for now. Eventually most of these tables should move into libsysdecode as the automated table generation approach from mksubr is less stale than the static tables in truss. Some changes have been made to truss and kdump output: - The flags passed to open() are now properly decoded in that one of O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded mask. - Optional arguments to open(), openat(), and fcntl() are only printed in kdump if they exist (e.g. the mode is only printed for open() if O_CREAT is set in the flags). - Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int. - Include all procctl() commands. - Correctly decode pipe2() flags in truss by not assuming full open()-like flags with O_RDONLY, etc. - Decode file flags passed to *chflags() as file flags (UF_* and SF_*) rather than as a file mode. - Fix decoding of quotactl() commands by splitting out the two command components instead of assuming the raw command value matches the primary command component. In addition, truss and kdump now build without triggering any warnings. All of the sysdecode manpages now include the required headers in the synopsis. 307948: Use binary and (&) instead of logical to extract the mask of a capability. 308602: Generate and use a proper .depend file for tables.h. 308603: Move libsysdecode-specific hack out of buildworld. This should fix the lib32 build since it was not removing the generated ioctl.c. This file is generated by a find(1) call, so cannot use normal dependency tracking methods. 311151: Update libsysdecode for getfsstat() 'flags' argument changing to 'mode'. As a followup to r310638, update libsysdecode (and kdump) to decode the 'mode' argument to getfsstat(). sysdecode_getfsstat_flags() has been renamed to sysdecode_getfsstat_mode() and now treats the argument as an enumerated value rather than a mask of flags.

This completes the fix for https://llvm.org/bugs/show_bug.cgi?id=26519. Differential Revision: https://reviews.llvm.org/D24466 Reported by: Mark Millard PR: 214433 MFC r309149: Pull in r283060 from upstream llvm trunk (by Hal Finkel): [PowerPC] Refactor soft-float support, and enable PPC64 soft float This change enables soft-float for PowerPC64, and also makes soft-float disable all vector instruction sets for both 32-bit and 64-bit modes. This latter part is necessary because the PPC backend canonicalizes many Altivec vector types to floating-point types, and so soft-float breaks scalarization support for many operations. Both for embedded targets and for operating-system kernels desiring soft-float support, it seems reasonable that disabling hardware floating-point also disables vector instructions (embedded targets without hardware floating point support are unlikely to have Altivec, etc. and operating system kernels desiring not to use floating-point registers to lower syscall cost are unlikely to want to use vector registers either). If someone needs this to work, we'll need to change the fact that we promote many Altivec operations to act on v4f32. To make it possible to disable Altivec when soft-float is enabled, hardware floating-point support needs to be expressed as a positive feature, like the others, and not a negative feature, because target features cannot have dependencies on the disabling of some other feature. So +soft-float has now become -hard-float. Fixes PR26970. Pull in r283061 from upstream clang trunk (by Hal Finkel): [PowerPC] Enable soft-float for PPC64, and +soft-float -> -hard-float Enable soft-float support on PPC64, as the backend now supports it. Also, the backend now uses -hard-float instead of +soft-float, so set the target features accordingly. Fixes PR26970.
