Subject: [PATCH] Add support for SerenityOS
|
||||
|
||||
Teaches the assembler, BFD, and the linker about the SerenityOS target
|
||||
triple.
|
||||
|
||||
On x86_64, we override the default base address of non-PIE executables,
|
||||
because the default (0x400000) is too close to the beginning of the
|
||||
address space, and DynamicLoader often ends up allocating internal data
|
||||
at that address. See commit 292398b5857d0104f7c33fdb5d79f45fe8b395dd.
