This commit fixes the following build error when the source code is build
with MinGW gcc 12 and compiler switch '-Werror=maybe-uninitialized' is
added:
'file.{anonymous}::OutputFile::old_mode_' may be used uninitialized
in this function [-Werror=maybe-uninitialized]
We currently do not set stdout to binary mode when writing a binary
file on Windows. This cause some extra characters to be written that
mess up the output. We try to fix that.
Fixes#4793
When a tool (tested with spirv-dis and spirv-as) runs on a file that
does not exist, it notifies the user and tries to close the stream that
was never successfully opened.
* Use standard function to get stdin to binary mode.
The fisrt implementation to try to change stdin to binary mode is not
protable. Using freopen has a lot of implementation defined behaviour,
and the code relied on that working.
Looking into the MSVC documentation, I do not see a protable way of
doing this. I've implemented a Windows specific method and do nothing
for other systems. In general, UNIX based systems do make a distinction
between text and binary files, so nothing needs to be done for them.
Fixes#2518
* Split ReadFile into two different functions.
We want to remove the flag parameter. So the original function has been
replaced with ReadBinaryFile and ReadTextFile. This should make the
code more readable.
* Change name of CorrectlyReadFile to avoid confusion.
[val] Add extra context to error messages.
This CL extends the error messages produced by the validator to output the
disassembly of the errored line.
The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.
Fixes#670, #1581
