Fix typo.

Implement APInt <-> APFloat conversion for IEEE 128-bit floats.
This fixes PR2555

llvm-svn: 79677

Add support for including '+' in APFloat strings, more asserts,
and many new unit tests.

llvm-svn: 79574

Fix two APFloat bugs in converting hexadecimal constants.

llvm-svn: 79540

Fix an uninitialized value warning in APFloat.

llvm-svn: 79353

Modify APFloat to take a StringRef instead of a c string.

This also adds unit tests to APFloat that mainly tests the
string handling of APFloat, but not much else of it's api.

llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Add support for letting the client choose different flavors of NaNs. Testcase to be
added in clang.

Fix whitespacing (space after switch).

llvm-svn: 71738

Fix internal representation of fp80 to be the
same as a normal i80 {low64, high16} rather
than its own {high64, low16}. A depressing number
of places know about this; I think I got them all.

of places know about this; I think I got them all.
Bitcode readers and writers convert back to the old
form to avoid breaking compatibility.

just initialize the first element, we don't need to set the rest to zeros.

Eliminate a 9640 byte static mutable initialized data item by moving it
to the stack. This shrinks all llvm tools by 9k, and improves reentrancy.

llvm-svn: 66847

static functions don't need an anonymous namespace.

Unbreak the build on win32.
Cleanup some warning.

Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.

Only tested with VS2008. hope it does not break anything. feel free to revert.

Make special cases (0 inf nan) work for frem.
Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

llvm-svn: 62645

Add an IEEE remainder function, which is not
fully implemented yet and not used. This is
mainly to clarify that APFloat::mod implements
C fmod, not remainder.

llvm-svn: 62593

compile-time fmod was done incorrectly. PR 3316.

llvm-svn: 62528

Get rid of bogus "control may reach end of non-void function ‘...’ being
inlined" message.

llvm-svn: 60165

Revert r60042. IndVarSimplify should check if APFloat is PPCDoubleDouble first before trying to convert it to an integer.

llvm-svn: 60072

convertToSignExtendedInteger should return opInvalidOp instead of asserting if sematics of float does not allow arithmetics.

llvm-svn: 60042

Add a "loses information" return value to APFloat::convert
and APFloat::convertToInteger. Restore return value to
IEEE754. Adjust all users accordingly.

llvm-svn: 57329

Rename APFloat::convertToAPInt to bitcastToAPInt to
make it clearer what the function does. No functional
change.

Mark negative-zero-to-int conversion as Inexact,
since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a
load-and-convert of int 0. Fixes
