Bump the version of config to the latest (3 year old, so upgrade worries are long past). Also remove redundant MACHINE= declarations and passing MACHINE/MACHINE_ARCH to module builds. That's now done in common code. 2014-02-04 18:24:25 +00:00			`%VERSREQ= 600012`

Add basic support for FDT to i386 & amd64. This change includes: 1. Common headers for fdt.h and ofw_machdep.h under x86/include with indirections under i386/include and amd64/include. 2. New modinfo for loader provided FDT blob. 3. Common x86_init_fdt() called from hammer_time() on amd64 and init386() on i386. 4. Split-off FDT specific low-level console functions from FDT bus methods for the uart(4) driver. The low-level console logic has been moved to uart_cpu_fdt.c and is used for arm, mips & powerpc only. The FDT bus methods are shared across all architectures. 5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the fdt_pic_table[] arrays. Both are empty right now. FDT addresses are I/O ports on x86. Since the core FDT code does not handle different address spaces, adding support for both I/O ports and memory addresses requires some thought and discussion. It may be better to use a compile-time option that controls this. Obtained from: Juniper Networks, Inc. 2013-05-21 03:05:49 +00:00			`INCLUDES+= -I$S/contrib/libfdt`

Add a kernel option for amd64 to compile with the frame on the stack so that the DTrace Function Bounadry Trace (fbt) provider can get coverage of most functions in the kernel. 2008-05-23 03:52:55 +00:00			`.if !empty(DDB_ENABLED) \|\| !empty(DTR_ENABLED) \|\| !empty(HWPMC_ENABLED)`
amd64: use -mno-omit-leaf-frame-pointer in addition to -fno-omit-frame-pointer ... in kernel builds. This is to make behavior of clang consistent with behavior of gcc. MFC after: 2 weeks 2013-07-09 08:42:02 +00:00			`CFLAGS+= -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer`

Upgrade our copy of llvm/clang to r126079, from upstream's trunk. This contains many improvements, primarily better C++ support, an integrated assembler for x86 and support for -pg. 2011-02-20 19:33:47 +00:00			`# XXX: clang integrated-as doesn't grok .codeNN directives yet`
Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to get rid of testing explicitly for clang (using ${CC:T:Mclang}) in individual Makefiles. Instead, use the following extra macros, for use with clang: - NO_WERROR.clang (disables -Werror) - NO_WCAST_ALIGN.clang (disables -Wcast-align) - NO_WFORMAT.clang (disables -Wformat and friends) - CLANG_NO_IAS (disables integrated assembler) - CLANG_OPT_SMALL (adds flags for extra small size optimizations) As a side effect, this enables setting CC/CXX/CPP in src.conf instead of make.conf! For clang, use the following: CC=clang CXX=clang++ CPP=clang-cpp MFC after: 2 weeks 2012-02-28 18:30:18 +00:00			`ASM_CFLAGS.acpi_wakecode.S= ${CLANG_NO_IAS}`
