Bug ID: 16413
Summary: ccc-analyzer filters too many compiler flags for
Pre-Compiled Headers
Product: clang
Version: 3.2
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer

ccc-analyzer patch to resolve this bug
If ccc-analyzer is run as part of a compilation which includes pre-compiled
header files, the analyze clang invocation fails with errors like these:
error: const-qualified string support was enabled in PCH file but is currently
disabled
error: __OPTIMIZE__ predefined macro was enabled in PCH file but is currently
disabled
error: exception handling was disabled in PCH file but is currently enabled
error: run-time type information was disabled in PCH file but is currently
enabled
To solve these problems, ccc-analyzer needs to pass along the following flags:
-Wwrite-string (since this actually implies -fconst-strings)
any -O level
all -f flags
This is perhaps not an exhaustive list, but I am able to complete an analysis
of WebKit by including these flags.
I have attached a diff (generated by git) against ccc-analyzer (clang-3.2)
which should fix these issues.
I believe clang-3.3 suffers from the same issues, but other bugs are preventing
me from fully testing it currently.
