This fragment is -repeated up to 16 times, and %%rsi and %%rdi are s and d on entry -respectively. Hence the complete asm statement reads 16 64-bit words -from memory starting at s, and writes 16 64-bit words starting at d. - -Without any declaration of modified memory, Clang 12 and Clang 13 generated -non-working code for mbedtls_mpi_mod_exp. The constraints make the unit -tests pass with Clang 12. - -Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com> ---- - include/mbedtls/bn_mul.h | 6 +++--- - 1 file changed, 3 insertions(+), 3 deletions(-) - -diff --git a/include/mbedtls/bn_mul.h b/include/mbedtls/bn_mul.h -index 6f1201bf50a..f84f9650ddc 100644 ---- a/include/mbedtls/bn_mul.h -+++ b/include/mbedtls/bn_mul.h -@@ -256,9 +256,9 @@ - "addq $8, %%rdi\n" - - #define MULADDC_STOP \ -- : "+c" (c), "+D" (d), "+S" (s) \ -- : "b" (b) \ -- : "rax", "rdx", "r8" \ -+ : "+c" (c), "+D" (d), "+S" (s), "+m" (*(uint64_t (*)[16]) d) \ -+ : "b" (b), "m" (*(const uint64_t (*)[16]) s) \ -+ : "rax", "rdx", "r8" \ - ); - - #endif /* AMD64 */ |
