Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.
find . -name "*.h" -exec clang-format -i {} \;
find . -name "*.cpp" -exec clang-format -i {} \;
It is valid for float values to be modified on copy if they are NaN,
so long as they remain the correct NaN. What this means is that
we can not rely on the float data-type for storing float values
if we want to retain bit patterns.
Added FloatProxy which stores data in an unsigned integer, and updated
the HexFloat template to deal with FloatProxy values instead.
This is an attempt to fix the unit tests on DeveloperStudio 2013.
Currently, the size of the earth_africa string is reported as 2
on Windows. But I think that may be 2 16-bit characters.
Versions 1.2, 2.0, and 2.1 all use the same
extended instruction list.
Updated the source code patch for the SPIR-V doc generator,
so it can both generate the core syntax table, and also the
OpenCL extended instructions table.
Tested the Math and Common functions.
TODO: test the remaining entries.
Except for OpConstant and OpSpecConstant, all other literal number
operands are indeed unsigned integers. So,
* Rename all *LITERAL_NUMBER* operand types to *LITERAL_INTEGER*.
* Expect unsigned integers for *LITERAL_INTEGER* operands.
* Keep MULITPLE_WORD_LITERAL untouched since it is only used by
OpConstant and OpSpecConstant.
And we want to provide the capability to specify floating-point
numbers after !<integer> in the alternate parsing mode. So,
OPTIONAL_LITERAL_NUMBER is reserved for OPTIONAL_CIV.
The DiagnosticStream will not emit the accumulated message
text if the error is SPV_FAILED_MATCH.
Change various interfaces to accept the intended error
code instead of a boolean "is_optional". This allows
us to avoid repeating the following type of logic deep
inside helper methods:
if (is_optional) return SPV_FAILED_MATCH;
return diagnostic() << " message text ";
Affects OpConstant, and OpSwitch.
Adds constant libspirv::kUnknownType for readability.
Adds tests for hexadecimal number parsing.
Updates syntax.md to describe hex parsing, including
sign extension.
Use this to shorten error return code in the assembler.
For example, change this:
if (error = something()) {
diagnostic() << " Bad integer literal " << value;
return SPV_ERROR_INVALID_VALUE;
}
to this:
if (error = something())
return diagnostic() << " Bad integer literal " << value;
Also shorten code due to the fact that binaryEncodeU32 and
binaryCodeU64 can't fail (short of failure to expand a std::vector).
