[gcc 4.1.1] many -Winline warnings

• Key: STDCXX-796
• Type: Bug
• Status: Open
• Priority: Major
• Assignee: Martin Sebor
• Reporter: Martin Sebor
• Component/s: Build and Installation
• Affects Version/s: 4.2.0
• Fix Version/s: 4.2.2

Description

Optimized builds with recent versions of gcc produce thousands of inlining warnings. See:

$ gunzip -c linux_redhat_el-5.0-em64t-gcc-4.1.1-12d-639851-log.gz | grep "inlining failed" | wc -l
4191

We should at least make an effort to silence those coming out of library headers (e.g., by applying #pragma GCC system_header but we might want to review them first to see if they could be used to optimize our code.

Scheduled for 4.2.2.

As a data point: in a 12D build of stdcxx with gcc 3.4.6 there are a total of 17,569 of these warnings. Only 121 of them are distinct (most are repeated occurrences pointing to the same piece of code), Of these 68 are in the library headers.
