2014-08-25xcompile: always use -march=i686Aaron Durbin
When compiling coreboot for x86 on gcc the compiler is free to pick whatever defaults it is using at the time of gcc's compile/configuration when no -march is specified. Not properly specifying -march then opens up the use of SSE instructions for compilation units it should not be used such as the SMM module as this module doesn't save/restore SSE registers.

2014-07-15build system: create .xcompile dependencyPatrick Georgi
It's probably safe to say that .xcompile needs an update if util/xcompile/xcompile changed, so tell make about this dependency. Updates are honored immediately due to GNU make's feature of reinterpreting everything when an included file changes. See "How Makefiles Are Remade" in the GNU make documentation for details.

This uses die() which was previously unused. Before this change an unhelpful error message was printed when make tried to parse English text as if it was part of the makefile: .xcompile:1: *** missing separator (did you mean TAB instead of 8 spaces?).

2013-01-04update CFLAGS for armv7David Hendricks
This updates $CFLAGS used for armv7. Most of them were just added to be consistent with what u-boot does. The important ones here are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions). I removed the hard float support because it got errors and coreboot should never use floats anyway. We're still having trouble with enums but I want to see how far it gets with this patch. Also, put the flags in a form that makes diffs easier to read. It's almost impossible otherwise. Finally, move some flags to the architecture Makefile, and rely on the fact that some are set for all architectures.

2012-03-03Use -mno-sse to prevent overzealous gcc optimizationsStefan Reinauer
The offending part that made coreboot crash with some toolchains was that gcc emits SSE instructions but coreboot did not enable SSE at that point. Since the gain for coreboot using SSE instructions is not measurable, let's not use SSE instructions rather than enabling SSE early on. One rationale behind this is that other parts of coreboot, like the SMM handler would need fixing because the XMM registers are not saved on SMM entry. Thus keep it simple.
