2013-09-08Fix handling of very long asm statements in inlinerAndi Kleen2-1/+12
An auto generated program with a 6.4mio line asm statement gave with 4.7 and 4.8: xxx.c:6400017:1: internal compiler error: in account_size_time, at ipa-inline-analysis.c:601 The problem is that the inliner counts the number of lines in the asm statement and multiplies that with a weight. With the weight this overflows 32bit signed int, and triggers an assert for negative time. Fix this by limiting the number of lines to 1000 for asm cost estimation. The RTL backend also does similar multiplications for jump shortening. I haven't tried to address this, but presumably it's less likely to result in a failure. gcc/: 2013-09-08 Andi Kleen <ak@linux.intel.com> * tree-inline.c (estimate_num_insns): Limit asm cost to 1000.
