Technical tradeoffs
- • Forcing the text-segment address to the maximum page size might increase the size of the executable file due to padding.
- • This change could potentially break existing applications that rely on the text-segment being loaded at a lower address, although this is unlikely.

[PATCH v2] elf: Set text-segment address to the maximum page size
This patch (v2) addresses an issue where the text-segment address of an ELF Position Dependent Executable (PDE) could be lower than the maximum page size specified on the command line. The patch modifies the linker to ensure that the text-segment address is set to the maximum page size when generating PDE output with the -z max-page-size=SIZE option. This prevents potential loading issues, particularly with PIE (Position Independent Executable), static PDE, and static PIE binaries, and includes added tests for these scenarios.
