The change is needed, because the previous version emitted multiple ".seh_handlerdata" blocks and GAS isn't able to merge them into one, but will instead only include the first one. This is fixed by generating "asm defines" in the code and pass the line number to the "REACTOS seh" pragma, which is then used to create all handler data by referring to the predefined symbols, that include the line number.
Also the EstablisherFrame parameter passed to the filter/finally function is the original stack pointer, not the frame pointer! Take this into account by passing __builtin_frame_address(0) from the filter context to the global wrapper function, which includes the frame-offset, and use that to recalculate the frame-pointer from the passed in stack pointer.
Also, put include directory next to the library and use
target_include_directories(.. INTERFACE ..) to get this right.
This is because :
- Having includes & implementation in two different places buggers me
- This makes sure that there is no "if it compiles everything is fine" behaviour from anyone
because now even static libraries need it for GCC amd64 build
Also add __USE_PSEH2__ define for the non SEH-aware compilers out there and use it in a few headers
where we define macros involving __try
