Probably you meant the reason it grows to 2GB. I believe it is caused by `-Wl,-Ttext=0x7d400000` (introduced in cbd2af9213fb76e2ed2e7d7a9151100f45f0679c). This option forces the `.text` segment to be placed at a high virtual address. When combined with `-Wl,--no-rosegment` (which is implicitly passed for older Android SDK levels), the linker changes how it groups sections into `PT_LOAD` segments. To preserve the required relation between virtual addresses and file offsets inside a `PT_LOAD` segment, the linker ends up assigning a very large file offset (`0x7d400000`) to the segment containing `.text`. This creates a huge sparse gap in the output file, making its apparent size close to 2GB.
