Tests an edge case in the RISC-V PSABI: In the medany and the medlow code models, the compiler emits auipc/lui (U-type) and ld/sw (I-type/S-type) instruction pairs for accessing a non-local symbol. The U-type instruction sets the upper 20 bits, the I/S-type the lower 12. The U-type and I-type/S-type instruction pairs are often adjacent in code. This is also what the current llext architecture-specific relocations expect. However, this need not be the case - compilers can re-use the upper 20 bits set by the U-type instruction with multiple I/S-type instructions, which is a useful optimization for multiple loads/stores of or within the same symbol. This commit adds a unit test for this behavior, which currently fails for RISC-V. Signed-off-by: Eric Ackermann <eric.ackermann@cispa.de> |
