From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.c-torture/compile/pr44784.c | 47 +++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr44784.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr44784.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr44784.c b/gcc/testsuite/gcc.c-torture/compile/pr44784.c new file mode 100644 index 000000000..54d531a3d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr44784.c @@ -0,0 +1,47 @@ +typedef struct rtx_def *rtx; +enum rtx_code { SUBREG }; +typedef union rtunion_def { + long rtint; + unsigned long rtuint; + rtx rtx; +} rtunion; +struct rtx_def { + enum rtx_code code: 8; + rtunion fld[1]; +}; +typedef struct simple_bitmap_def { + unsigned long long elms[1]; +} *sbitmap; +struct df_link { + struct df_link *next; + rtx reg; +}; +typedef enum { UNDEFINED, CONSTANT, VARYING } latticevalue; +typedef struct { + latticevalue lattice_val; +} value; +static value *values; +static sbitmap ssa_edges; +void defs_to_varying (struct df_link *start) +{ + struct df_link *currdef; + for (currdef = start; + currdef; + currdef = currdef->next) + { + rtx reg = currdef->reg; + if (values[(reg->code == SUBREG + ? reg->fld[0].rtx + : reg)->fld[0].rtuint].lattice_val != VARYING) + ssa_edges->elms [(reg->code == SUBREG + ? reg->fld[0].rtx + : reg)->fld[0].rtuint / 64] + |= ((unsigned long long) 1 + << (reg->code == SUBREG + ? reg->fld[0].rtx + : reg)->fld[0].rtuint % 64); + values[(reg->code == SUBREG + ? reg->fld[0].rtx + : reg)->fld[0].rtuint].lattice_val = VARYING; + } +} -- cgit v1.2.3
