This patch adds a test to make sure offsets that are not legal for non-prefixed DS/DQ instructions are legal for a prefixed instruction. This test has been in the master branch since June, and no changes were needed to backport it to GCC 10. Can I check this into the GCC 10 branch? gcc/testsuite/ 2020-08-03 Michael Meissner Backport from the master branch: 2020-06-27 Michael Meissner * gcc.target/powerpc/prefix-ds-dq.c: New test. --- gcc/testsuite/gcc.target/powerpc/prefix-ds-dq.c | 161 ++++++++++++++++++++++++ 1 file changed, 161 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/prefix-ds-dq.c diff --git a/gcc/testsuite/gcc.target/powerpc/prefix-ds-dq.c b/gcc/testsuite/gcc.target/powerpc/prefix-ds-dq.c new file mode 100644 index 0000000..554cd0c --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/prefix-ds-dq.c @@ -0,0 +1,161 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target powerpc_prefixed_addr } */ +/* { dg-require-effective-target lp64 } */ +/* { dg-options "-O2 -mdejagnu-cpu=power10" } */ + +/* Tests whether we generate a prefixed load/store operation for addresses that + don't meet DS/DQ offset constraints. 64-bit is needed for testing the use + of the PLWA instruciton. */ + +struct packed_struct +{ + long long pad; /* offset 0 bytes. */ + unsigned char pad_uc; /* offset 8 bytes. */ + unsigned char uc; /* offset 9 bytes. */ + + unsigned char pad_sc[sizeof (long long) - sizeof (unsigned char)]; + unsigned char sc; /* offset 17 bytes. */ + + unsigned char pad_us[sizeof (long long) - sizeof (signed char)]; + unsigned short us; /* offset 25 bytes. */ + + unsigned char pad_ss[sizeof (long long) - sizeof (unsigned short)]; + short ss; /* offset 33 bytes. */ + + unsigned char pad_ui[sizeof (long long) - sizeof (short)]; + unsigned int ui; /* offset 41 bytes. */ + + unsigned char pad_si[sizeof (long long) - sizeof (unsigned int)]; + unsigned int si; /* offset 49 bytes. */ + + unsigned char pad_f[sizeof (long long) - sizeof (int)]; + float f; /* offset 57 bytes. */ + + unsigned char pad_d[sizeof (long long) - sizeof (float)]; + double d; /* offset 65 bytes. */ + __float128 f128; /* offset 73 bytes. */ +} __attribute__((packed)); + +unsigned char +load_uc (struct packed_struct *p) +{ + return p->uc; /* LBZ 3,9(3). */ +} + +signed char +load_sc (struct packed_struct *p) +{ + return p->sc; /* LBZ 3,17(3) + EXTSB 3,3. */ +} + +unsigned short +load_us (struct packed_struct *p) +{ + return p->us; /* LHZ 3,25(3). */ +} + +short +load_ss (struct packed_struct *p) +{ + return p->ss; /* LHA 3,33(3). */ +} + +unsigned int +load_ui (struct packed_struct *p) +{ + return p->ui; /* LWZ 3,41(3). */ +} + +int +load_si (struct packed_struct *p) +{ + return p->si; /* PLWA 3,49(3). */ +} + +float +load_float (struct packed_struct *p) +{ + return p->f; /* LFS 1,57(3). */ +} + +double +load_double (struct packed_struct *p) +{ + return p->d; /* LFD 1,65(3). */ +} + +__float128 +load_float128 (struct packed_struct *p) +{ + return p->f128; /* PLXV 34,73(3). */ +} + +void +store_uc (struct packed_struct *p, unsigned char uc) +{ + p->uc = uc; /* STB 4,9(3). */ +} + +void +store_sc (struct packed_struct *p, signed char sc) +{ + p->sc = sc; /* STB 4,17(3). */ +} + +void +store_us (struct packed_struct *p, unsigned short us) +{ + p->us = us; /* STH 4,25(3). */ +} + +void +store_ss (struct packed_struct *p, signed short ss) +{ + p->ss = ss; /* STH 4,33(3). */ +} + +void +store_ui (struct packed_struct *p, unsigned int ui) +{ + p->ui = ui; /* STW 4,41(3). */ +} + +void +store_si (struct packed_struct *p, signed int si) +{ + p->si = si; /* STW 4,49(3). */ +} + +void +store_float (struct packed_struct *p, float f) +{ + p->f = f; /* STFS 1,57(3). */ +} + +void +store_double (struct packed_struct *p, double d) +{ + p->d = d; /* STFD 1,65(3). */ +} + +void +store_float128 (struct packed_struct *p, __float128 f128) +{ + p->f128 = f128; /* PSTXV 34,1(3). */ +} + +/* { dg-final { scan-assembler-times {\mextsb\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mlbz\M} 2 } } */ +/* { dg-final { scan-assembler-times {\mlfd\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mlfs\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mlha\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mlhz\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mlwz\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mplwa\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mplxv\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mpstxv\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mstb\M} 2 } } */ +/* { dg-final { scan-assembler-times {\mstfd\M} 1 } } */ +/* { dg-final { scan-assembler-times {\mstfs\M} 1 } } */ +/* { dg-final { scan-assembler-times {\msth\M} 2 } } */ +/* { dg-final { scan-assembler-times {\mstw\M} 2 } } */ -- 1.8.3.1 -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meissner@linux.ibm.com, phone: +1 (978) 899-4797
