to the extent needed to make ppc32 work. * As a result, remove the replacements for glibc's floor/ceil fns on ppc32/64, since vex can now correctly simulate the real ones. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@5605

ALL THE CODE IN THIS FILE RUNS ON THE SIMULATED CPU.

|
|
These functions are not called directly - they're the targets of code
|
|
redirection or load notifications (see pub_core_redir.h for info).
|
|
They're named weirdly so that the intercept code can find them when the
|
|
shared object is initially loaded.
|
|
|
|
Note that this filename has the "vg_" prefix because it can appear
|
|
in stack traces, and the "vg_" makes it a little clearer that it
|
|
originates from Valgrind.
