# As glibc does not support decimal floating point, the types to
# consider for generic parameters are standard and binary
# floating-point types, and integer types which are treated as double.
# The corresponding complex types may also be used (including complex
# integer types, which are a GNU extension, but are currently disabled
# here because they do not work properly with tgmath.h).

# The proposed resolution to TS 18661-1 DR#9
# <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2149.htm#dr_9>
# makes the <tgmath.h> rules for selecting a function to call
# correspond to the usual arithmetic conversions (applied successively
# to the arguments for generic parameters in order), which choose the
# type whose set of values contains that of the other type (undefined
# behavior if neither type's set of values is a superset of the
# other), with interchange types being preferred to standard types
# (long double, double, float), being preferred to extended types
# (_Float128x, _Float64x, _Float32x).

# For the standard and binary floating-point types supported by GCC 7
# on any platform, this means the resulting type is the last of the
# given types in one of the following orders, or undefined behavior if
# types with both ibm128 and binary128 representation are specified.

# If double = long double: _Float16, float, _Float32, _Float32x,
# double, long double, _Float64, _Float64x, _Float128.

# Otherwise: _Float16, float, _Float32, _Float32x, double, _Float64,
# _Float64x, long double, _Float128.

# We generate tests to verify the return type is exactly as expected.
# We also verify that the function called is real or complex as
# expected, and that it is called for the right floating-point format
# (but it is OK to call a double function instead of a long double one
# if they have the same format, for example).  For all the formats
# supported on any given configuration of glibc, the MANT_DIG value
# uniquely determines the format.
