TCG does not distinguish signed int from unsigned int, because they are the same size. However, we need to retain this distinction for dh_typecode, lest we fail to extend abi types properly for the host call parameters. This bug was detected when running the 'arm' emulator on an s390 system. The s390 uses TCG_TARGET_EXTEND_ARGS which triggers code in tcg_gen_callN to extend 32 bit values to 64 bits; the incorrect sign data in the typemask for each argument caused the values to be extended as unsigned values. This simple program exhibits the problem: static volatile int num =3D -9; static volatile int den =3D -5; int main(void) { int quo =3D num / den; printf("num %d den %d quo %d\n", num, den, quo); exit(0); } When run on the broken qemu, this results in: num -9 den -5 quo 0 The correct result is: num -9 den -5 quo 1 Fixes: 7319d83a735 ("tcg: Combine dh_is_64bit and dh_is_signed to dh_typeco= de") Resolves: https://gitlab.com/qemu-project/qemu/-/issues/876 Reviewed-by: Alex Benn=C3=A9e Reported-by: Christian Ehrhardt Tested-by: Christian Ehrhardt Tested-by: Keith Packard Signed-off-by: Richard Henderson --- include/exec/helper-head.h | 19 ++++++++++--------- target/hppa/helper.h | 2 ++ target/i386/ops_sse_header.h | 3 +++ target/m68k/helper.h | 1 + target/ppc/helper.h | 3 +++ 5 files changed, 19 insertions(+), 9 deletions(-) diff --git a/include/exec/helper-head.h b/include/exec/helper-head.h index b974eb394a..734af067fe 100644 --- a/include/exec/helper-head.h +++ b/include/exec/helper-head.h @@ -53,13 +53,16 @@ # ifdef TARGET_LONG_BITS # if TARGET_LONG_BITS =3D=3D 32 # define dh_alias_tl i32 +# define dh_typecode_tl dh_typecode_i32 # else # define dh_alias_tl i64 +# define dh_typecode_tl dh_typecode_i64 # endif # endif -# define dh_alias_env ptr # define dh_ctype_tl target_ulong +# define dh_alias_env ptr # define dh_ctype_env CPUArchState * +# define dh_typecode_env dh_typecode_ptr #endif =20 /* We can't use glue() here because it falls foul of C preprocessor @@ -92,18 +95,16 @@ #define dh_typecode_i64 4 #define dh_typecode_s64 5 #define dh_typecode_ptr 6 -#define dh_typecode(t) glue(dh_typecode_, dh_alias(t)) +#define dh_typecode_int dh_typecode_s32 +#define dh_typecode_f16 dh_typecode_i32 +#define dh_typecode_f32 dh_typecode_i32 +#define dh_typecode_f64 dh_typecode_i64 +#define dh_typecode_cptr dh_typecode_ptr +#define dh_typecode(t) dh_typecode_##t =20 #define dh_callflag_i32 0 -#define dh_callflag_s32 0 -#define dh_callflag_int 0 #define dh_callflag_i64 0 -#define dh_callflag_s64 0 -#define dh_callflag_f16 0 -#define dh_callflag_f32 0 -#define dh_callflag_f64 0 #define dh_callflag_ptr 0 -#define dh_callflag_cptr dh_callflag_ptr #define dh_callflag_void 0 #define dh_callflag_noreturn TCG_CALL_NO_RETURN #define dh_callflag(t) glue(dh_callflag_, dh_alias(t)) diff --git a/target/hppa/helper.h b/target/hppa/helper.h index fe8a9ce493..c7e35ce8c7 100644 --- a/target/hppa/helper.h +++ b/target/hppa/helper.h @@ -1,7 +1,9 @@ #if TARGET_REGISTER_BITS =3D=3D 64 # define dh_alias_tr i64 +# define dh_typecode_tr dh_typecode_i64 #else # define dh_alias_tr i32 +# define dh_typecode_tr dh_typecode_i32 #endif #define dh_ctype_tr target_ureg =20 diff --git a/target/i386/ops_sse_header.h b/target/i386/ops_sse_header.h index e68af5c403..cef28f2aae 100644 --- a/target/i386/ops_sse_header.h +++ b/target/i386/ops_sse_header.h @@ -30,6 +30,9 @@ #define dh_ctype_Reg Reg * #define dh_ctype_ZMMReg ZMMReg * #define dh_ctype_MMXReg MMXReg * +#define dh_typecode_Reg dh_typecode_ptr +#define dh_typecode_ZMMReg dh_typecode_ptr +#define dh_typecode_MMXReg dh_typecode_ptr =20 DEF_HELPER_3(glue(psrlw, SUFFIX), void, env, Reg, Reg) DEF_HELPER_3(glue(psraw, SUFFIX), void, env, Reg, Reg) diff --git a/target/m68k/helper.h b/target/m68k/helper.h index 9842eeaa95..0a6b4146f6 100644 --- a/target/m68k/helper.h +++ b/target/m68k/helper.h @@ -17,6 +17,7 @@ DEF_HELPER_4(cas2l_parallel, void, env, i32, i32, i32) =20 #define dh_alias_fp ptr #define dh_ctype_fp FPReg * +#define dh_typecode_fp dh_typecode_ptr =20 DEF_HELPER_3(exts32, void, env, fp, s32) DEF_HELPER_3(extf32, void, env, fp, f32) diff --git a/target/ppc/helper.h b/target/ppc/helper.h index ab008c9d4e..ae7d503fcf 100644 --- a/target/ppc/helper.h +++ b/target/ppc/helper.h @@ -127,9 +127,11 @@ DEF_HELPER_FLAGS_1(ftsqrt, TCG_CALL_NO_RWG_SE, i32, i6= 4) =20 #define dh_alias_avr ptr #define dh_ctype_avr ppc_avr_t * +#define dh_typecode_avr dh_typecode_ptr =20 #define dh_alias_vsr ptr #define dh_ctype_vsr ppc_vsr_t * +#define dh_typecode_vsr dh_typecode_ptr =20 DEF_HELPER_3(vavgub, void, avr, avr, avr) DEF_HELPER_3(vavguh, void, avr, avr, avr) @@ -708,6 +710,7 @@ DEF_HELPER_3(store_dbatu, void, env, i32, tl) =20 #define dh_alias_fprp ptr #define dh_ctype_fprp ppc_fprp_t * +#define dh_typecode_fprp dh_typecode_ptr =20 DEF_HELPER_4(DADD, void, env, fprp, fprp, fprp) DEF_HELPER_4(DADDQ, void, env, fprp, fprp, fprp) --=20 2.25.1 From nobody Wed Apr 16 16:47:53 2025 Delivered-To: importer@patchew.org Authentication-Results: mx.zohomail.com;
