* [Bug c/25246] New: [gomp] #pragma pack() inside of structure @ 2005-12-03 19:37 jakub at gcc dot gnu dot org 2005-12-08 8:55 ` [Bug c/25246] " jakub at gcc dot gnu dot org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: jakub at gcc dot gnu dot org @ 2005-12-03 19:37 UTC (permalink / raw) To: gcc-bugs #pragma pack(1) struct S { char h; int i; #pragma pack() int j; }; struct S s; void *i = &s.i, *j = &s.j; (distilled from Linux kernel) used to compile in 4.0.x, though the whole struct wasn't really packed at all (i at offset 4, j at offset 8). gomp #pragma handling rejects this. Another testcase is: #pragma pack(1) struct S { char h; struct T { int h1; char h2[3]; } t; int i; #pragma pack() int j; }; struct S s; void *i = &s.i, *j = &s.j; void *h1 = &s.t.h1, *h2 = &s.t.h2[0]; Here, h1 was s+1, h2 s+5, i s+8 and j s+12, i.e. struct T used to be packed and struct S wasn't packed. -- Summary: [gomp] #pragma pack() inside of structure Product: gcc Version: 4.1.0 Status: UNCONFIRMED Keywords: openmp Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25246 ^ permalink raw reply [flat|nested] 4+ messages in thread
