Remapper errors are generally fatal: there has been some unexpected situation while
parsing the SPV binary, and there is no reasonable way to carry on. The
errorHandler() function is called in this case, which by default exits, but
it is possible to submit a handler which does not. In that case the remapper would
carry on in a bad state.
This change ensures a graceful termination of the remap() function.
While a try {} catch {} construct would be the ideal and safe way to do this,
that's off limits for certain environments, so this tries to do the same thing
with explicit code, to catch all the bailout paths.
- fixed ParseHelper.cpp newlines (crlf -> lf)
- removed trailing white space in most source files
- fix some spelling issues
- extra blank lines
- tabs to spaces
- replace #include comment about no location
If some DCE is performed such as removing dead functions, then even
if we are NOT stripping debug info, we still must remove the debug
opcodes that refer to the now-dead IDs.
Also, this adds a small change to perform no ID remapping if none
is requested, making spirv-remap properly be a no-op if no options
are given.
This reverts commit ad08b30f696267ec6243dd0ad68a3db889cd2d21, reversing
changes made to 28660bb580d4c61e16ef75008550a87b3be90b91.
This backs out the pull request
https://github.com/KhronosGroup/glslang/pull/456 because it introduced
several internal errors even on code that only uses 32-bit numeric
types.
