aee49255 - Recommit: Compress formatting of array type names (int [4] -> int[4])

Thu, 14 Oct 2021 21:52:47 +0000

Recommit: Compress formatting of array type names (int [4] -> int[4])Based on post-commit review discussion on2bd84938470bf2e337801faafb8a67710f46429d with Richard Smith.Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -they're all around pointer/reference types where the pointer/referencetoken will appear at the rightmost side of the left side of the typename, so they make nested types (eg: the "int" in "int *") behave asthough there is a non-empty placeholder (because the "*" is essentiallythe placeholder as far as the "int" is concerned).This was originally committed in 277623f4d5a672d707390e2c3eaf30a9eb4b075cReverted in f9ad1d1c775a8e264bebc15d75e0c6e5c20eefc7 due to breakagesoutside of clang - lldb seems to have some strange/strong dependence on"char [N]" versus "char[N]" when printing strings (not due to that nameappearing in DWARF, but probably due to using clang to stringify typenames) that'll need to be addressed, plus a few other odds and ends inother subprojects (clang-tools-extra, compiler-rt, etc).

f9ad1d1c - Revert "Compress formatting of array type names (int [4] -> int[4])"

Thu, 14 Oct 2021 21:48:17 +0000

Revert "Compress formatting of array type names (int [4] -> int[4])"Looks like lldb has some issues with this - somehow it causes lldb totreat a "char[N]" type as an array of chars (prints them outindividually) but a "char [N]" is printed as a string. (even though theDWARF doesn't have this string in it - it's something to do with thestring lldb generates for itself using clang)This reverts commit 277623f4d5a672d707390e2c3eaf30a9eb4b075c.

DR1413 and part of P1815R2: Minor improvements to Clang's determinationof type- and value-dependency.A static data member initialized to a constant inside a class templateis no longer considered value-dependent, per DR1413. A const but notconstexpr variable of literal type (other than integer or enumeration)is no longer considered value-dependent, per P1815R2.

Fri, 23 Apr 2010 02:41:41 +0000

C++ doesn't really use "namespaces" for different kinds of names the sameway that C does. Among other differences, elaborated type specifiersare defined to skip "non-types", which, as you might imagine, does notinclude typedefs. Rework our use of IDNS masks to capture the semanticsof different kinds of declarations better, and remove most current lookupfilters. Removing the last remaining filter is more complicated and willhappen in a separate patch.Fixes PR 6885 as well some spectrum of unfiled bugs.llvm-svn: 102164 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/typedef-redecl.cpp

Tue, 15 Dec 2009 20:14:24 +0000

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/typedef-redecl.cpp

Thu, 19 Feb 2009 23:45:49 +0000

Fix a long standard problem with clang retaining "too much" sugar information about types. We often print diagnostics where we say "foo_t" is bad, but the user doesn't know how foo_t is declared (because it is a typedef). Fix this by expanding sugar when presentin a diagnostic (and not one of a few special cases, like vectors).Before:t.m:5:2: error: invalid operands to binary expression ('typeof(P)' and 'typeof(F)') MAX(P, F); ^~~~~~~~~t.m:1:78: note: instantiated from:#define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^After:t.m:5:2: error: invalid operands to binary expression ('typeof(P)' (aka 'struct mystruct') and 'typeof(F)' (aka 'float')) MAX(P, F); ^~~~~~~~~t.m:1:78: note: instantiated from:#define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^llvm-svn: 65081 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/typedef-redecl.cpp
