This makes the statically linked binaries to use fast gettimeofday(2) by forcing the linker to resolve references and providing the neccessary functions. 2012-09-22T12:38:19Z Konstantin Belousov kib@FreeBSD.org 2012-09-22T12:38:19Z urn:sha1:f351b8e841a22a1d5aef4ca5f46907537528bc7c Use struct vdso_timehands data to implement fast gettimeofday(2) and clock_gettime(2) functions if supported. 2012-02-21T21:18:59Z Konstantin Belousov kib@FreeBSD.org 2012-02-21T21:18:59Z urn:sha1:889519990c112ae585c4bd7ef06e9de368172ef5 Add API for obtaining extended machine context states that cannot be fit into existing mcontext_t. On i386 and amd64 do return the extended FPU states using getcontextx(3). For other architectures, getcontextx(3) returns the same information as getcontext(2). MFC r230864: Make the sys/ucontext.h self-contained by changing the return type of __getcontextx_size(3) from size_t to int. 2011-12-30T18:18:06Z Konstantin Belousov kib@FreeBSD.org 2011-12-30T18:18:06Z urn:sha1:5df9446b423420070ad0c86aa37a0f62d36e9b00 Make sure that stack is 16-byte aligned before calling a function, as it is required by amd64 ABI. Add a comment for the places were the stack is accidentally properly aligned already. PR: amd64/162214 2011-07-21T20:06:14Z George V.

This leaves us with just five implementations. Suggested by: bde Approved by: rpaulo (mentor)
