Meta: Add a script check the presence of "#pragma once" in header files .. and make travis run it. I renamed check-license-headers.sh to check-style.sh and expanded it so that it now also checks for the presence of "#pragma once" in .h files. It also checks the presence of a (single) blank line above and below the "#pragma once" line. I also added "#pragma once" to all the files that need it: even the ones we are not check. I also added/removed blank lines in order to make the script not fail. I also ran clang-format on the files I modified. 2020-05-28 20:40:53 +02:00

Kernel: Fix various forward declarations I decided to modify MappedROM.h because all other entried in Forward.h are also classes, and this is visually more pleasing. Other than that, it just doesn't make any difference which way we resolve the conflicts. 2020-09-12 00:44:54 +02:00			`struct PtraceRegisters;`

LibDebug: Use InputMemoryStream instead of BufferStream. This removes another call to ByteBuffer::wrap(const void*, size_t). 2020-08-05 10:55:36 +02:00			`Value evaluate(ReadonlyBytes, const PtraceRegisters&);`
