| |
Hi,
This is the fifth iteration of a patch series to ensure that all SGX selftests succeed when compiling with optimizations (as tested with -O{0,1,2,3,s} for both gcc 11.3.0 and clang 14.0.0). The aim of the patches is to avoid reliance on undefined, compiler-specific behavior that can make the test results fragile.
Reference output below:
.. Testing gcc -O0 [OK] .. Testing gcc -O1 [OK] .. Testing gcc -O2 [OK] .. Testing gcc -O3 [OK] .. Testing gcc -Os [OK] .. Testing gcc -Ofast [OK] .. Testing gcc -Og [OK] .. Testing clang -O0 [OK] .. Testing clang -O1 [OK] .. Testing clang -O2 [OK] .. Testing clang -O3 [OK] .. Testing clang -Os [OK] .. Testing clang -Ofast [OK] .. Testing clang -Og [OK]
Changelog ---------
v5 - Reorder patches (Jarkko, Kai) - Include fixes tag for inline asm memory clobber patch (Kai) - Include linker error in static-pie commit message (Kai) - Include generated assembly in relocations commit (Kai)
v4 - Remove redundant -nostartfiles compiler flag (Jarkko) - Split dynamic symbol table removal in separate commit (Kai) - Split redundant push/pop elimination in separate commit (Kai) - Remove (incomplete) register cleansing on enclave exit - Fix possibly uninitialized pointer dereferences in load.c
v3 - Refactor encl_op_array declaration and indexing (Jarkko) - Annotate encl_buffer with "used" attribute (Kai) - Split encl_buffer size and placement commits (Kai)
v2 - Add additional check for NULL pointer (Kai) - Refine to produce proper static-pie executable - Fix linker script assertions - Specify memory clobber for inline asm instead of volatile (Kai) - Clarify why encl_buffer non-static (Jarkko, Kai) - Clarify -ffreestanding (Jarkko)
Best, Jo
